But of course I'm aware of the butt dyno effect (when I wax my car and change the oil, it 'feels' faster too so I know that such things are subjective). >>It has 225s on there now, which is the OEM tire. >>Nothing wider than that is needed I agree. > > Also... let me point out that some people are very fond of putting all-terrain > tires with aggressive tread on SUVs, and then they wonder why the handling on > the road is poor. I agree with you but this is a 2wd which has never been off the shoulder of the road, so, I don't need poser tires. I treat it like a car. > This happened to a friend of mine; the tire place sold her > some tires that would have been a very good choice offroad, and she wondered > why her rear-end was hopping so much off the line. Going back to proper road > tires helped a lot. I wish there was some good way of testing tires out beforehand to "feel" them but it's just impossible. The best you can do is ask friends and read reviews, but everyone has different requirements and not everyone has the same vehicle driven the same way (and even if they do, they don't always say it in the reviews). So while I like to buy my tires on pure logic, in tires most of that information is just not available to you for all the tires you might be considering. Therefore, I often have to buy tires on published specifications alone, where the OEM specifications are my starting point (e.g., the load range and speed range and air pressure and camber and toe, etc.). It's all homework + logic. Just like it was at school to get a perfect GPA. |

> The logic is *you get what you pay for*. If that were actually true, then you just threw 100 years of Marketing research out the window. They teach you in business school that you *never* get what you pay for (and that the people you want to sell your stuff to are those who *think* you get what you pay for). They always tell us to have a "good/better/best" lineup, because people *want* to pay more for "better" stuff, but at the same time they teach us about 'economies of scale' where you slightly differentiate the product (e.g., gold-plated trim) so that people will *think* that it's a better product (even though it's the same product). Seriously, if anyone truly thinks that you "get what you pay for", they have never taken a single marketing class in their life because that statement is never true. Marketing people can influence prices greatly, where all you get is a lot of marketing when you pay more for something that you can easily get for less. > Cheap tyres do not perform as well as good quality tyres. I'm really sorry to have to be blunt with you, but the only people who say that are people who compare objects by price are those who known nothing about the object but they do know numbers so that's why they pick price. The MARKET sets the price. Do you really think, for example, that a $50,000 Rolex Watch tells better time than a $50 Timex watch? > I never buy cheap tyres for my car(s). What you care about in tires is measureable "stuff" such as size, traction, temperature generation, load range, treadwear, noise, comfort, and handling. If you can get better "stuff" for less money, then you're paying more for worse tires. The iron-clad logic of what I say is inescapable, although I'm never going to convince anyone who thinks "you get what you pay for" that they are falling for the oldest trick in the (marketing) book so I do not expect you to believe a word I am saying. > When the OEMs wear out, I usually fit > Michelins which I have found are not a great deal dearer than the OEM, > and in some cases cheaper, but they grip like baby**** on a blanket. To > me, grip on the road is a factor worth paying for. If you buy tyres on > price alone, you are doing yourself a disservice. Where did I ever say I buy *anything* on price alone? Do I look like a person who doesn't use logic when making spending decisions? I took too many marketing classes in school to fall for a price-only comparison. The only things you buy on price alone are commodities. Depending on your perspective, anything (even tires) can be considered a commodity - but you and I both do not consider tires to be a commodity. Propane fuel is a commodity to many people but that doesn't stop marketing organizations from trying to differentiate their product line (which is what marketing organizations do). To me, propane from supplier X is the same as propane from supplier Y even though supplier X might try to tell me their trucks are prettier or faster or somehow better than supplier Y. If tires were a commodity to you and to me, then buying on price would be fine - but neither of us thinks that tires are a commodity. This is basic marketing 101 so if I'm wrong, then the past thousand years of business teaching is all wrong and you're right that "you get what you pay for". |

I would be very, very suspicious of anyone who did this. They likely have some kid who knows how to put numbers into the machine doing the job, instead of an alignment expert doing the work. It's going to take the tech about half an hour to do the suspension check over....going around pulling on things and hitting things with a mallet and getting some sense of the general condition of the suspension. Then he is going to spend ten or fifteen minutes talking with you about how you drive, THEN he's going to start measuring the suspension. So figure an hour's time for a full-priced technician just to look everything over. >> Also, you do not need a "4 wheel" alighnment. > >I've been reading up on alignment where the Toyota only has front >camber/caster (which is one setting) and toe, so that's all I need are >those two things. What you MOST need is the guy pushing and prodding and hitting things with a hammer to make sure everything on the suspension is stable. The actual alignment on the machine is the easy part and the less important part. You take it to the tire store, they put it on the machine, they measure it, they put shims in so everything looks good on the machine and they declare it aligned. But if you have anything loose and worn, it will be out of alignment again by the time you get it out of the shop. Before putting it on the machine you need to verify this isn't the case. >If I can find a shop who will do those two CHECKS for around $25 that would >make logical sense. > >But to pay for an entire mounted tire just to save on a mounted tire seems >like throwing good money away logically as it was aligned two years ago >(and at that time, it needed it because the front left was wearing really >fast). It's maintenance. Every 3,000 miles you change the oil, and you look over all the hoses and belts and check the fluid levels just to make sure everything is okay. You're not wasting time or money doing the check just because it _is_ okay. You spend the time or money to make sure it stays that way. Every once in a while you need to check the state of the suspension as well. And yeah, finding someone who actually knows what they are doing and who can do a careful alignment is rare, and it's worth supporting that person. --scott -- "C'est un Nagra.

Have a look at SAI (Steering Axis Inclination) as well. SAI and caster angles usually increases the positive camber angle of the inside tire and decreases positive camber angle of the outside tire during a turn though this will depend on the steering system employed. This is a designed in effect that you can easily and inadvertently affect when playing around with other angles. Unless you have a really good understanding of steering geometry, you are playing around in the dark. -- Xeno |

Some conditions require more. My wife's car can happily exist on $100 tires. She rarely goes on the highway, never drives in snow, rarely goes more than a few miles at a time. OTOH, I drive some weeks 2000 miles. speeds sometimes in triple digits, on hills in the snow, on highways in the heat. Do you think the $100 tire is going to perform as well as a Nokian WR3G? It is about double the price but can keep you safer in severe condition. I don't buy on price and minimum specs, I buy on the performance that I need. A cheap screwdriver can drive the occasional screw, but if you do it often you'll find the more expensive ones fit your hand better and thus work better. Meantime, enjoy your hamburger. I'm having a steak. |

I'm really sorry to have to be blunt with you, but you are not translating this to your real life situation. Seems like you only care about measurable stuff like meeting minimum requirements, not how the suit your particular needs. I do realize you don't really get what you pay for. If you pay 50% more you are probably getting 25% more in performance, but you have to decide if you need/want that performance. I drive a fully loaded, every available option higher end car. I can get to the store just as fast in a cheap stripped down economy model that is a better value but I choose not to. It was a choice. The only value is what I justify to myself. > > If you can get better "stuff" for less money, then you're paying more for > worse tires. Sometimes. How are your tires working?

I never buy on price. Hence it's a given that my tires are better than the OEM tires. Better speed rating. Better load carrying capacity. Better traction. Better treadwear. Quieter tread (less aggressive than OEM since I don't go off road). Knowing how manufacture's aim for economies of scale, I am sure my tires cost more than the OEM tires did, but I don't aim for price. I aim for logical value. |
