Replying to: obyone (Jul 20, 2009 9:06 pm) Thanks, something else I'll have to mess around with now. I almost traded this car a couple of months ago and I stashed my receipts somewhere when I cleaned out the car. Not sure where they are now.
#6951 of 7006 How many people really discard all their tires after 10 years? by woodyww Jul 24, 2009 (9:52 am)
If you had 10 y.o. unused tires (almost new-looking), properly stored, no dry rot, would you really throw them out, & buy new tires for a vehicle you drive 3K miles a year? I know the "correct" answer, but..... Replies to this message: capriracer (Jul 25, 2009 3:15 am) woodyww (Jul 25, 2009 9:37 am) explorerx4 (Aug 21, 2009 12:58 pm) and 3 more...

Replying to: woodyww (Jul 24, 2009 9:52 am) It is understandable that folks would be reluctant to throw away what appears to be a perfectly good tire. The problem is that the deterioration of the rubber is real and it is both time and temperature dependent. In other words, the results in Phoenix would be different than the results in Minneapolis. Plus, the signs that the rubber has deteriorated do not appear on unused tires. Flexing is required for the cracks to develop. And cracking is a sign that things are bad - lack of cracking doesn't mean things are good. You also have to consider that a tire failure at 70 mph could cause potentially fatal resuts, where a 25 mph would probably not be so dramatic. Needless to say, an old tire would be much more prone to failure than a fresh one. Last thought: The scenario you've proposed means that at 15,000 miles, the tire would be 15 years old. Does this sound like a good idea? Replies to this message: woodyww (Jul 25, 2009 9:37 am) explorerx4 (Aug 21, 2009 12:58 pm) woodyww (Aug 23, 2009 12:14 pm) and 2 more...

Replying to: capriracer (Jul 25, 2009 3:15 am) capriracer, yeah, I know everything you're saying is true. My car failed Mass. inspection the other day, because of the current tires on my 10 y.o. bmw, which do look pretty bad. My plan--just because I have the other "new" looking 10 y.o. tires in my garage already mounted on nice bmw rims--is to have those put on to pass inspection--at least they'll be better than the current worn-out tires, I assume. Then in Oct., have my new Dunlop snows mounted on the "old" rims that are on the car now. And look for a good deal on new summer tires in the meantime.....& cool it at highway speeds.....most of my driving is around town anyway. OTOH, my local Costco has Michelin - Pilot® Exalto® A/S 225/55R16 tires at a decent price, + a $70 coupon off. They get exc. consumer ratings on Tire Rack. I know there are other cheaper choices, but it would be easy for $500-ish.....

#6954 of 7006 wider tires by jeffyscott Jul 28, 2009 (12:18 pm)
I have a car that has 195/65-15 tires on steel wheels. Other versions of this car came with tires as wide as 225/45-17. I assume this means that 215/70-15 tires could fit the car width-wise. I am also guesing that extra ~1 inch radius would still allow enough clearance. But is it safe to assume that the wider tires would fit on the existing wheels? I understand that these tires would create a bit of error in speedometer readings, online calculator indicates it'd be off about 7.5%. Would there be any other issues with doing this?

Replying to: jeffyscott (Jul 28, 2009 12:18 pm) You have to be mindful of rim width and offset. Even though, yes, it seems like a tire up to 225mm would fit, no, I wouldn't guarantee that a 215/70-15 would fit. You probably have a 6" wide rim which means a 215 may fit on there-- each tire size has recommended and allowable rim widths. But that's a tall tire and even though it's narrower than a 225/45-17, we don't know the rim width and offset of the 15 and 17 inch wheels... so even if you could mount the tire on the rim, it might rub the fenders or struts. Proceed carefully... unless you're sure someone has tried the same combination you're thinking of, and it worked fine for them. Replies to this message: jeffyscott (Jul 28, 2009 3:16 pm)

Replying to: jeffyscott (Jul 28, 2009 12:18 pm) An extra 1" of radius is a huge difference.. I'm not sure why you would assume that would give you enough clearance.... You don't say what car this is... From the sizes, I'm going to guess a sporty FWD hatchback... like a VW GTI? Or an Impreza? Way too tall..

Replying to: colin_l (Jul 28, 2009 12:39 pm) On tire rack it comes up with 6.5 inch wide steel rims for this car, so I would guess that is what is on there. It gives 45 mm as the offset for 15 inch and 42 mm for 16 inch. For 17 inch alloys it shows +45 mm offset, and it also indicates 19 inchers could be put on with in a 235/35 size. I'd check with the dealer before doing this. I'm just looking for potential use for newish tires on a minivan that could potentially be disposed of as a clunker and I happen to have a Jetta that will need tires soon. edit: sounds like this wouldn't work.
#6958 of 7006 Tires of different age by pepito51 Aug 16, 2009 (12:44 pm)
I have an SUV, and a few years ago (at 38,000 miles) I backed over a trailer hitch and blew a tire. So I bought 2 new tires. I'm now at 78,000 miles--the pair of original Michelin Cross Terrain tires have 78,000 miles on them; the newer pair (same kind) has 40,000 miles on them. While the 78,000 pair (8 years old) show more wear, they're not in bad shape as far as I know, and no treadwear indicator is visible. But is that getting to be too many miles to have on a pair of tires, and if so, would people normally buy 2 new tires or 4 and get them "synchronized" again? Thanks for info.
