I searched and read everything and still can't find an answer. I have a 2013 GS 350 f sport awd.
F 20x9 +30 235/30/20
R 20x10 +35 255/30/20
the wheel diameter variance is %1.85
Will this be ok to run or is the ovarall rolling diameter off to much. Should I put 235/35/20 on the fronts?

I think you might be able to get more help in the 4GS section, as this is the 2IS section. In my opinion, the variance you posted of 1.85% is too much. I always kept my tire size variance to less than 1% on my 2007 GS350 AWD and never had an issue for almost 100k miles. Of course, YMMV.
Why not do something like 235 or 245/35 and 275/30.... I thought the 4GS can take a wider tire than the 3GS?

I just used a tire calculator and the difference is 0.99%. I'm looking to use 245/35R19 front and 275/30R19 rear. This is from my ISF and want to use on my wife's 08 is250 awd. Just want to confirm this setup would be ok to use with the awd system?
Thanks in advance!

I'm looking for the same, I want to run 245/35 and 275/30. Thats 85.75mm tall front and 82.5mm tall rear. Can anyone confirm if this is within 1%? Or do I need to run the 235/40?

running a 10/11 on my awd rc350 fsport and ideally the 30mm tire difference width wise is best for the 25mm difference in wheel width.

^^I'm assuming you're referring to 19" wheels? Here is what the tire calculator says based on what I think you are asking (closest match to 275/30/19 is a 235/35/19)

These are my two options




The 235/35/19 and 275/30/19 is spot on and same rolling diameter, but I built a 10/11 for my RC350. I may have to switch to an 11.5 to keep an even stretch, or size down to the 265/30 which has a .08% variance difference. 1" wheel difference would be closes to a 30mm tire difference, unless I went wider in rear to accomidate the bigger tire.

Any thoughts?

May the gurus please shine some light on this, these wheels caught my eye but wasnt sure if itll ruin my AWD

19x9.5 +22
19x10.5 +18
225/35 and 245/35

Is the rolling diameter too off ?

Based on this calculator:http://www.1010tires.com/Tools/Tire-...5R19/245-35R19
Its 2.19% diameter variance, NO, I wouldn't run that on my AWD. Under 1% is maximum I would go.

Hi Guys,

Planning to run 19x9 +35 and 19x9.5 +38.

Would it make more sense to go 235/35/19 all around or would I still need to go 265 or 275/30 in the back?

Thanks

tire sizes will be 235/35 275/30 which is same sidewall height, stretch, and 0% variance down to the mm. 😎

I may re lip to 10.5 & 12" this week with 245/35 and 285/30. This was to easy to fit and I want to push the limits.
