I am about to purchase MRR H2 rims for my 350. They will be 19 inch 8.5 in the front and 9.5 in the rear. The place I am getting the rims from are having a hard time matching up tires to fit.
225x35 in the front = lots of options
265x35 in the rear = not many options
275x30 in the rear = more options but the guy says that the overall diameter is too small and that the width is "out of the spec"

My question is :
Should I go with the 265x35 or the 275x30?
What are the pros and cons?
If I put the 275will I notice a difference in the handling because they are so wide?
Anyone with pics of MRR H2? I know there are pics out there but search is not working for me.

 

I have 275/30 Falkens on my 19x10 rims in the rear and have no issue.

 

I don't think they make 270 wire tires

 

Go with the 265's. I'd also try to get some 235/35's in the front so you don't increase the differential in width. The car already understeers and increasing that differential will increase the understeer.

 

will 235x35 look the same as 225x35 on an 8.5 rim?
will it bulge out on the sides?

I like the way the stock tires look on the stock 18" rims.
I would like the new tires on the 19" rims to have a lower profile.

Thanks, I don't know squat about tires and rims.

 

I have those Hereborrani HR-2 rims on my 07 GS350, have a look under GS – third generation, then under “Official 2006 GS Modification Thread!!” last posts 546 and 547. I list the size of the rims and tires size for 20”. I also own a IS350, I think the IS maybe the same as GS, anyway check it out. I just looked at MRR rims hope your refering to the HR-2 or is there a H2 rim.

 

235fronts and 265 rears, you can get away with 275 but keep in mind you might have rubbing issues, unless you mod your fender. I have the same rims size, and everyone Ive talked to said the same thing.

 

I have 275 on my rear on a 19x10 rim. My car is lowered with Eibach Pro Kit and no rubbing even with people in the back.

 

225's on 8.5" wheels will look very stretched. You want either 235's or 245's on 8.5"s. 235's will not look like they're bulged.

 

You have 19x10 so you need 275 minimum. Good offsets you have thats why youre not rubbing, its not the size of the rim its the offset that makes a difference.
