View Full Version : Mixing and Matching Tires?

I need to replace my front tires (goodyear rs-a). The rears (michelin symmetry) have only 10k on them. Although the Symmetry tires are okay, I'd like to get some killer all-season shoes for the front b/c that's where the power's at! Something like Michelin Pilot Sport A/S. Then eventually they'd move to the rear and I'd get a second pair of Mich A/S. Is there anything wrong with this approach?

Well, you would go back and fourth between replacing front/rear, always have some semu-worm tires on the car, and never have a brand new set of rubber.....

I used to wonder why someone coudln't get 2 differnt types of tires for the front and back, based on drivetrain to change the way their car performs.....

..... I would still personally go with 4 of the same make/model

Personally, as long as their the same age, i see no problem.... I have a set of warrior tires in the back and coopers in the front..... As long as their the same size, its ok, IMO. If there different ages, then when the oldest set it replace them.....

Or in your case, you could leave the new ones on until the treadwear is about the same on the front and rear, and then rotate them.

I've been told that as long as they are the same tires on the same axle, it's ok, otherwise handling could be affected. Personally, I find Michelins (longer lasting with a higher tread wear number) not good on snow or ice because softer tires are better for all season. IMO

Ralph's right to a point. Mixing tires on the same axle is never a good idea but any mixing of tires on the car period is less than optimal.

ah, good points...I imagine that if I put sweet handling tires up front, the rears wouldn't be able to keep up, and handling would be odd. I'm gonna go with the Symmetrys up front and hope that they wear down in unison with the rears or at least catch up so that one day, I can but on 4 awesome tires. By that time tho, I'm hoping to have a new CTSv!

if they are the same size and the same speed rating you should be fine. but dont go mixing a Z+ rated tire with an H or lower rated tire, then you end up with one hard end and one soft end and you could fin yourself in a whole mess of trouble.

kinda off topic, but i also heard that if you get a flat, or a blow out, and it is on your drive axel, that you should take a wheel off a non-drive axel, put that on the drive axel, and put the spare on the non-drive axel (all this only applies to the little donut tires) becuase I heard if you drive with the smaller tire on your drive axel for extended periods of time, it will casue alot of extra friction and heat within the differental and wear it down alot faster (1 wheel is always spinning faster then the other)

I guess I meant that or should have also mentioned that I would not mix different speed ratings, or different brands of the same size on the same axle. etc. I thought or meant to imply that. I would personally always use the same tires on the same axle. Even the treadwear number can mean 1 tire is softer than the other. Yeah, I am leary of putting the "mini metric" or "donut" spare tires and leaving it too long. I have seen people leave the donuts on for quite a long time before they get their full size regular tire fixed, this can not be good for handling in the long run. Mind you, in -40 degree weather I would rather struggle with a smaller spare tire than a heavier full-sized.:)
