Replying to: oldfarmer50 (Aug 24, 2009 9:22 am) The rubber compound actually does not perform at low temperatures, to the point that it will be noticeably hard and slick instead of grippy. A high performance vehicle (which is what most summer tires are mounted on) will not brake, corner or even accelerate as well if you do use a summer tire in cold, dry temperatures.

Replying to: colin_l (Aug 24, 2009 11:03 am) "...will not brake,corner or even accelerate as well..." That's what I thought. So it's a matter of reduced performance rather than having something happen to the integrity of the tire itself. In other words the tire won't blow up if you drove it in winter.

Replying to: oldfarmer50 (Aug 26, 2009 9:13 am) ".........That's what I thought. So it's a matter of reduced performance rather than having something happen to the integrity of the tire itself......." There is one possibility that I should point out. Rubber compounds have "glass transition temperatures", where the properties change at given temperatures. These will vary from compound to compound - and ceratin between manufacturers. But there is a temperature below which rubber compounds tend to become brittle and crack. This, of course, also varies from compound to compound. In most cases, this temperature is bitterly cold - say below -20°F Nevertheless, it is good advice that summer tires should not be used below 40°F.
#6971 of 7006 advice needed by stickguy Sep 13, 2009 (7:44 pm)
I have a 2000 Acura TL. My sons car, that is now my "spare" car since he is away at college (freshman). There is, however, a chance that I sell my other car and just keep the TL until next summer when he needs it again. Anyway, the tire issue. Discovered recently that 1 tire (RF) has a small sidewall bulge (an impact break from the couple of tire guys that looked at it). Probably has been there for a while, since the kid remembers hitting a big pothole back in late winter/early spring, and there is some cracking around the bump. question is two fold: How dangerous is it to drive with, and what should I do to replace? tires on car are 4 years old, 58K on them, but still with ~4/32 tread (very evenly worn too). OEM replacement Micheling (MXV4, maybe energy? Something I don't think they make anymore). Too much wear to replace 1 (and the comparable tire tends to be a ridiculous price). I have never been a fan of replacing just 2 tires, but right now, I am not a fan of spending much money on this car. So, how much will I notice (actual drving, not the mental aspect of knowing about it and having it bug me) if I put 2 other tires on one end? Have been considering Eagle GT (for price), Yoko Avids, and Potenza G019 girds. For now, I am only using the car around town a couple days per week to give it some exercise, so maybe 30-40 miles local? Am I taking my life in my hands ignoring the issue for a while? And, would I be nuts to put on just 2 tires, even though the rears have a decent amount of life on them? Replies to this message: jeffyscott (Sep 14, 2009 6:00 am) mz6greyghost (Sep 14, 2009 6:05 am)

car drives fine. Perfect alignment, no vibration at all even at highway speed (damn thing has better tire balance then my other 2 cars!)

Replying to: stickguy (Sep 13, 2009 7:44 pm) 4/32nds is the new 2/32nds and some would say your tires are worn out...assuming there is rain from time to time. http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=51 http://www.consumerreports.org/cro/cars/tires-auto-parts/tires/how-safe-are-worn- -tires/overview/

Replying to: stickguy (Sep 13, 2009 7:44 pm) Firstly, ANY tire with a bulge in the sidewall is dangerous, and should be replaced immediately. A bulge usually indicates a structural deformity in the sidewall, which significantly increases the chance of a blowout... As for replacements, personally, I think that 4/32nds is about time to change into new tires, and I'd do all four, because although it may be your "spare" car, it's still also your sons, which I'm sure he'll drive it when he's home. I'd feel safer with four new tires compared to two new tires and two others that are on their last rotation. As for brands, there are plenty of choices that are around or below $100 each that are good choices. Check out Tirerack.com. I also recommend the Yoko Avids, since they are on my Mazda6, and have been excellent in all aspects of traction and wear for a decent price... Good luck.
#6975 of 7006 clarification by stickguy Sep 14, 2009 (7:54 am)
I pulled out the last report on the TL. As of the last oil change (1K ago) the Honda dealer said it had 6/32 all the way around. I thought they looked better than 4! The original tires on the car (same model) made it to 91K, but I have no idea how bald they were at that point.
#6976 of 7006 Kelly Chargers by stickguy Sep 14, 2009 (10:20 am)
Turns out that they still make Kelly springfield tires. Got a good price quote on Kelly CHarger GTs. Looked nice enough, and had A traction and temperature ratings. Anyone have any experience or thoughts on these?
