I've had two different staggered setups on my car over about a 10k mile range. No issues so far with either. The current 245/45/19 and 275/40/19 setup is exactly 27.7" tall.

 

haha, the worst of all seasons...or best?

 

Just wanted to thank you for this post! Really useful information.

 

No Issues

 

How many miles is this?

 

Anyone seeing or notice any negative effects ? Got my eye on 225/45/19 front and 245/40/19 rear for my awd just want to know if anyone’s had long term since this was last visited

 

I think you are better off with 225/45 & 255/40. Its a much nicer pairing dimensionally as it is almost identical circumference, vs. a little over -1% with a 225/45 - 245/40, meaning the rear would be slightly smaller in diameter, which you have to remember will likely grow over time as the rear tires tend to wear a little faster than the front. I have been running staggered 225/45 - 255/40 for a little over two years without any issues.

 

what about if I ran 225/40 245/40?

 

No I wouldn’t do that, that puts you at a 2.3% variance which might not sound like a lot but it means that over the course of a mile the front tires would have something like 19 more rotations than the rear. This increases the likelihood of the AWD system having issues. The goal is to keep variance as close to 0 as possible with a general rule of thumb to not go over 1%... and ideally the taller tire would be in the rear as over time it would wear a little faster and get closer to 0%. Our site has a nice Tire/Rim calculator where you can plug in the different tire/wheel sizes and offsets to compare and see what would be best.

Curious, why you’re thinking about going staggered? A square setup is probably a little more ideal if the G is your daily driver. You could always run 245/40 all the way around. It’s a really common tire size so there are lots of options and then you can more readily rotate them. Staggered is nice for going wider in the rear for some extra traction or if you have a wider wheel. I’m actually likely to switch to 245/40 & 285/35.

 

thanks for this. I Just got some 370z Nismo wheels 19x9.5 +40
19x10.5+23 and have been looking for tire combos.

13 g37xs

 

I recently purchased a brand new set of wheels 19x9.5 +22. They came wrapped in Continental DWS06+ 245/45/19 275/40/19. They were originally intended for a G37 coupe RWD. My 14’ Q60 S Coupe is AWD though. I just want to make sure, before writing them off and having to buy a new set of tires, that they’ll work without any issues.? Thanks!

 

Those tires have matching rolling diameters and will be no issues for your awd. Its a bit taller than the oem diameter (~26.7 inch). Those tires have a diameter of ~27.7 inch, about an inch taller. There's no real negatives to this other than your speedometer will be slightly off and depending how low you are, may limit clearance, but no significant.

 

I seen a really nice setup on a RWD G37. They were using 265/35/19 front and 275/35/19 rear. Is this fine for AWD?

 

the diameter difference between those two sizes is roughly 1.1% But this is just the nominal size.

because every tire model varies with the actual tire diameter so the real diameter percentage difference can be more or less.

I always recommend to stay under 1% but 1.1% is pretty close and shouldn't cause problems with awd. I am starting to find that having the larger diameter in the rear seems to be better also.
