Hi Fellow Members....I have been visiting Fresh Alloy's G35 Forum and there is fairly active thread going on wheel rotation. Apparently Infiniti has not come to the table with an official recommendation on rotation other than don't do it. Some post recommend breaking the tires off the rim and switching side to side to get best wear. Here is my question: Is it reasonable to assume us 6MTCoupers can run the rear size 245/24R 18's in the front as well as rears. If there is truly no design or performance dynamics affected, this seems like a reasonable approach to replacement tire sizes when that day comes. I am concerned at what I read about 15-20K Michelin Pilot Sports replacement + having to switch tires completely off the rims and exchange position side to side. So if there is no significant, technical reason for not running the 245's all the way around I plan on doing so. What does everyone think...it's an issue facing all 6MT Coupers as well as Z owners. If it is doable....rotation time will not be an issue or PIA,

I might not be as knowlagable as others on this forum about wheels and such.. but the G's setup with different size tires in the front and rear helps with traction...

..pestilence..

Officially, Infiniti does not recommend anything wider than 225 in the front of the coupe or sedan. Anything wider may cause rubbing with suspension parts. Unofficially, 235 is probably okay, maybe 245 as well.

However, it's a high-performance vehicle. You put high-performance tires on it that don't last long anyway. You aren't going to get that much better tire life out of rotating them. I think as long as you watch the tire pressure and alignment closely, you should be fine.

Of course, you could drop back to some long-life touring tires and give up some performance.. put some 60k mile tires on in the first place and drive it like a family car. Then rotation may help.

When it comes to high performance cars (and their tires) rotating tires isn't a very good idea. Sports cars tend to "break in" each axles tires in a different way, and when you take the rears off and put them on the front, or move the left tires to the right, etc., it makes the car handle strange, at least until the tires get "broken in" again. The tires on the back of the coupe are wider and taller for a reason, and the suspension is calibrated for a staggered setup. I would at least keep them staggered, and I personally wouldn't bother with rotating tires. If I wear them out, (most likely the rears[img]/w3timages/icons/smile.gif[/img]), I'll just replace them. I chalk it up to just another little sacrifice to the high performance gods...

Hey Folks...thanks a bunch. Your input was just what I was looking for. Lets run em' all the way. Interesting comments on the staggered set-up. By the way...I carry a digital tire pressure gage and manual air pump in the coupe...I do not like using gas station equipment...the bike pump works great and you always have the capability to adjust and inflate tires in with you right in your trunk.

Driving to the gas station heats your tires up, thus increasing the air pressure. Most PSI reading are cold measured. I suppose you could take a cold pressure before you leave home to go to the gas station and then again when you arrive and subtract the difference, but that's sorta a PITA.

Gas Station pumps can sometimes have damaged or defective valve depressors. I have on a couple of occassions years ago damage my tire valve using some of these depressors. I do the bike pump because it's conveinent, and also should you be somewhere with a slow leak you can handle the problem on the spot. My pump is manual. Normally to increase pressures say from 28psi to 35 psi is about 10 to fifteen handle pumps....not all that bad.
