Temporarily mixing tires (Page 1/1) Valkyrie MAY 31, 03:44 PM Recently, one of the tires in my G8 has developed a bit of a bulge in the sidewall. Rather than risk a blowout, I've temporarily changed all four tires to some brand new winter tires (studless) I had sitting around from a previous car. Not fond of these winter tires in the summer months as they ride a bit rough and don't jive with the look of the car. I have one new tire (matching in make, model, and size) to replace the tire that has a bulge. However, the remaining three are quite worn. I'm not crazy about mixing old and new tires, but here's the dilemma: I am purchasing 4 new tires (different make and model) online but have a 2,500km/1,550mi journey (one way, 5,000km/3,100mi total) coming up real soon and will have to leave before the new tires would arrive at my current location. I am going to be at my destination for two weeks, so if I order now, they could arrive there and I could have new tires for the remaining 2,500km/1,550mi. My question is, with matching/evenly worn tires in the rear, how hard is it on the car to have one worn and one new tire on the front for a 24 hour drive? My only real concern is that in some round-about kind of way, this will have some adverse effect on the suspension, or perhaps put extra stress on the other front tire. Worst case scenario is I leave the winter tires on for the entire trip and replace them when I get back. However, if the new/old thing isn't any concern when they're on the front, I'd rather not have to sport them and deal with the poor ride for 48 hours. Any insight is much appreciated! davylong86 MAY 31, 06:28 PM Im no tire expert but I would take the evenly worn tires on back and move them up front put the mix match in the rear. I would think that would handle a little better. Is this the racing G8 your taking? tesmith66 MAY 31, 06:31 PM It's a G8. You can wear match that newer tire to the worn out ones pretty fast Valkyrie MAY 31, 06:34 PM quote Originally posted by davylong86: Im no tire expert but I would take the evenly worn tires on back and move them up front put the mix match in the rear.

Unless I'm mistaken, I was always under the impression mixing tires on drive wheels is a big no-no as it's hard on the drivetrain. quote Originally posted by tesmith66: It's a G8.

Does your car have a posi rear end? Otherwise, I don't see it hurting anything. If anything, it will be like driving on a very gently sweeping curve. One wheel may make a handful of revolutions more than the other, in a mile. Depending upon how picky it is, it may confuse your traction control if one tire is of a slightly different diameter. If you get a chime and a traction control/ABS light, you'll know why. I wouldn't even think it would matter, except I have a G6 with traction control and I got an intermittent chime/light with mine, 3 or 4 times. It hasn't happened since I replaced the tires, which were worn unevenly. (Backs were worse than fronts.) YMMV Valkyrie MAY 31, 07:39 PM It is a limited slip in the rear, yeah. I have no problem putting the two evenly worn tires on the rear, so I imagine this is even less of an issue in the front end. carnut122 MAY 31, 10:49 PM quote Originally posted by Valkyrie: It is a limited slip in the rear, yeah.
