Replying to: corvette (Mar 12, 2005 1:03 pm) The problem is there are no defined standards, such as; utoq 400, traction AA, temp A. So direct or indirect comparisons can be made but it would be hard to say they are valid. However the fact that it is an OEM product with back up marketing hype is (unfortunately) the surest sign. The reason why is pretty simple. One real world measure is they want to be able to get the highest fuel mileage to publish with a straight face. Or more importantly not to get sued!! ") (:. So it behooves them to put in the LEAST rolling resistant tires as possible!! So for example on a VW Jetta TDI three "lower resistant" tires come oem. In rank order by poll of actual owners in the real world 1. Michelin MXV4 plus 2 Continental ContiContact Touring CH95 3 Goodyear Eagle LS-H.

Replying to: ruking1 (Mar 13, 2005 8:03 am) Thanks... Looks like he will probably go with the Michelins again. Replies to this message: ruking1 (Mar 17, 2005 12:28 pm) mkhphillips (Mar 19, 2005 9:47 am) steve_ (Mar 19, 2005 9:48 am)
#4548 of 7006 BF Goodrich Precept or Goodyear Allegra by vs4 Mar 15, 2005 (1:10 pm)
Hello All, I am in the market for new set of tires for my car and have narrowed it down to BF Goodrich precept and Goodyear Allegra tires, both of them are available in Canada through Canadian Tire. I am confused on which one to buy, I am having tough time to figure out which one is more quieter and has better traction than the other one. I asked the service advisor at Canadian tire and he is saying Goodyear (reason they sell more of those and the tread pattern). I also did a quick search at Edmunds and found GoodYear Allegra tire referred in discussion forums a lot more than BF Goodrich Precept. I would like to know if anybody has Goodyear Allegra or BF Goodrich Precept tires on there car and what there experience has been like? Also from anybody else who has heard any good or bad things about these two tires? Thanks for all of your help.

Replying to: corvette (Mar 13, 2005 9:41 am) Best of luck!! Also just as another poster has said the Michelin MXV4's has a few models. I hope he got the correct one for his needs. Replies to this message: mkhphillips (Mar 19, 2005 9:47 am) steve_ (Mar 19, 2005 9:48 am)
#4550 of 7006 RARE Japanese wheels. PLEASE HELP!!! by mkhphillips Mar 19, 2005 (9:47 am)
Replying to: ruking1 (Mar 17, 2005 12:28 pm) I desperately need help on finding these wheels. They are called "Supersonic" and they are made in Japan (I think). I am having a very hard time finding anyone who sells them. I was told that they were introduced to the US about 7 months ago. The only company that I can find them through is QRS Auto Group, Inc. (www.wheeltechnology.com/product-supersonic.php). The middle man is selling them on eBay. I tried to purchase them through him but he said that the company was not responding. The company came to him at last year's SEMA show in Las Vegas. Like I said before, I am in desperate need of these wheels (20") for my Avalanche (Z71). Any help would be greatly appreciated. I can be contacted at “MikeMikeandKaren.cc”. Thanks, Mike Replies to this message: steve_ (Mar 19, 2005 9:48 am)

#4552 of 7006 Re: I was just informed today by a tire..... by marsha7 [capriracer] by imidazol97 Mar 19, 2005 (10:07 am)
Replying to: capriracer (Mar 13, 2005 4:16 am) Capriracer: I was critized in another forum when I repeated your statement in this forum about 100 psi for burst pressure minimum. I had responded to a post that 44 psi was a burst pressure and that tires should not be inflated more than 1 or 2 pounds above the maker recommended pressure. The same post said the tires had to have a rounded sidewall or "otherwise the sidewalls will not flex enough to provide proper handling, ride control, etc." But I've always felt handling was better with 3 or 5 pounds more in the tires, especially fronts on FWD. Is that right or is control better with lower pressures? I've had a variety of cars with FWD, Century, LeSabre. But I even felt that true with RWD Mustang and Torino 73. How about that pressure above doorpost?

Replying to: alext (Sep 27, 1999 2:54 pm) Does anyone own this gauge? It's from Michelin. What is your opinion on this gauge.? Im thinking of getting a digital gauge and came across the Michelin gauge. How does it compare to the accutire gauge? Replies to this message: steve_ (Mar 19, 2005 8:22 pm)

#4555 of 7006 Re: Tire Burst Pressure by imidazol97 by capriracer Mar 20, 2005 (5:31 am)
I saw that post (actually the series of posts), and....ah....well, may be things could have been worded better. (me included!) There isn't a "Minimum Burst Pressure" - like a standard or a regulation. It turns out that if you design a tire correctly, you wind up with static burst pressures well over 100 psi. So it's just a consequence, not an intended result. What is molded on the sidewall is a usage upper end. It is also true that more inflation pressure does increase the risk of impact type failures - a "burst", if you will. But characterizing what is molded on the sidewall as some sort of maximum for "burst" purposes is as wrong as thinking that what people do on the race track has a bearing on what people should do on the street. (Racing is such a peculiar activity from a vehicle operational point of view.) Yes, more inflation pressure does improve steering response (how quick the tire, and therefore the vehicle, reacts to steering input) it also reduces the amount of heat generation and how much a tire "rolls over" on cornering - which is why folks use 40 to 50 psi in FWD cars when racing on "street" tires. I also recommend 3 to 5 psi above the placard inflation - but that's a general rule and not always appropriate - and I do that based on my understand of what methodology is used to set the placard pressures. Part of my recommendation is based on my preference for a "crisper" steering response, but also on the idea that sacrificing a bit of ride softness and getting many improvements (hydroplaning resistance, durability, treadwear,etc) is just a good trade-off. Hope this helps.
