Yes as a whole I've heard very good reviews on the Atturos, and for the price they can't be beat, plus I like the look of the tread pattern. I was originally set on Nitto 555 G2's, but I simply don't like the way the tire looks. Petty I know, but the primary reason for swapping new tires/rims is aesthetics, I'm not tracking the car or driving in anything other than warm sunny weather. I'm still on the fence on whether to go with Gloss Black or Gun Metal MRR's , but I'm leaning heavy towards Gloss Black.

IMO gloss looks best on fancy cars. I probably would not go with Atturos but I guess they could be better than the run flats.

wont the 35 series rub the strut in the front?

I don't think they will, they will be the same height as the OEM 245/40's that were on there. I currently have 285/30's on the front, so 275/35 will be slightly taller (but no taller than the OEM 245/40) and slightly narrower...

Yes the factory 245/40/20 are approx 27.7" tall and 9.8" wide.


The 275/35/20 are approx 27.6" tall and 10.9" wide.


The 285/30/20 are approx 26.8 tall and 11.4" wide.


I believe there is a slight difference in the factory rims having a 20 offset, and the MRR's having a 23 offset.

Not sure I was discussing this with you a few weeks back, but keep in mind your speedo. I have the 20x10s all around with 285 30 20s and my speedo is off by 2-3 mph, depending on speeds (the higher the speed, the more the variation. 75mph on speedo is actually 72. Otherwise, 0 complaints.

This is true, it is what I've observed especially at highway speeds.

Yes that was me....I really like the look of your square set-up. The 285/30's are about an inch shorter than factory spec, so they will definitely throw off your speedo, as would a taller 305/35 or 315/35. The 315/30 is essentially identical in height to the factory 275/35 rears.


I use the online calculator to show offset and mph variances with different wheel combos.

When comparing the factory front 245/40/20 on a 8.5" rim 20 offset, to a 275/35/20 on a 10" rim 23 offset, I just don't see how the 10" front rim will clear the front strut brace, do you have any issues with rubbing in the front ? I don't have mag ride if that makes a difference.

The OEM SS front rims are a 25 offset (not 20)... I currently have 285/30 on 10.0" wide (23 offset) on the front with no rubbing issues (I have Mag Ride)...

The OEM offset on 10" rims is 20 not 25. OEM offset 25 is for 8.5" front wheels not 10". And your 23 offset is right at the maximum aspect ratios at 285 wide. I'm running 285/35R20 on my front with an offset of 20 based on 1LE wheel size without issue. You'd probably see rubbing if you ever went to a 35 aspect on your 23 offset wheel.

I'm aware, I was talking about the OEM SS (Non-1LE) offset being 25 (on the 8.5" wheel)... So where would the rubbing be expected? On the side of the tire? You think there is only 3mm of clearance on your setup? Wouldn't running 275/35's make up for the 3mm of offset difference?

Technically yes, the tire width is almost 1 full centimeter less than 285's, so higher aspect would be ok in that case. But the problem on 10" wheels is the wheel rim is over the lip of the tire, instead of the tire lip being over the wheel rim.

I have pictures of that on my car with 275/30R20's 285's fit better on the 10" wheel, the rest regarding offset has to do with internal rubbing inside the wheel well, mainly with suspension linkages if I am not mistaken. You would see rubbing on the inside of the tire. And some people have shown pictures of it stripping the tire down to the wire. So premature tire wear.

I guess 275/30 would be the smallest I would go on a 10" rim, 265's will likely not fit the rim itself due to sealing issue. I guess that would translate to less tire flex on hard turns? The 35 aspect should help with tire flex in that case.

If the factory 8.5" rim is a 25 offset, that would explain why there is minimum clearance between my rim and strut. The clearance is maybe pinky width at most, I would think a 10" 23 offset rim would rub, or be within a hair of rubbing the strut.


Does anyone know if Mag Ride has the same clearances as non Mag Ride?

What's interesting is on Atturo's website they say the 285/30 is good for a 9.5" - 10.5" wheel, but the narrower (and taller) 275/35 is good for a wider range of wheel width, from 9.0" - 11.0"... I'm assuming due to the taller sidewall being able to reach the wider/narrow rim...

Either way, a 10.0" wheel is right in the middle of both tires recommended wheel width...





I don't think they rim will stick out beyond the sidewall of the tire on the 275/35's on a 10.0" rim...
