I have a 2014 IS250 F-Sport, Incurve IC-S10 20" wheels 20x9 front 20x10.5 rear, rear offset is +45. Rear tires are 275/30/20, debating between RS*R down, and Tien S-Tech springs, don't want to rub in the rear, opinions???

I'm on 20's with rsr downs no rubbing at all but my rear tires are 255/30

 

I am running 20x9/20x10.5 Vossen CV5 front offset is 38 rear is 45 225/30/20 front tire and 255/30/20 rear tire with rsr down springs and no rubbing issues. I am actually going to get 235/30/20 in the front when I go for new tires.

 

Thank you, my tires are already mounted I didn't want sooo much of a stretched look so I went with the 275's, I have a feeling its going to rub bad

 

I have a one finger gap with my 255's in the rear so 275 is going to be really bad. You may have to get new tires that are smaller or roll your fenders.

 

same here but 275 will rub!

 

So crazy, so nobody at all on here is running 275's? My 275's are a bit stretched now I couldnt imagine a 255

 

I run 265/30 on 19x10.5 et45 and can tell it rubs a little during hard corners.

 

I'm on 275s on 19 inch wheels with a 38 offset, I am not lowered at all and when i first got the tires they rubbed a little over some bumps.... with stiffer spring rate I don't think that I would have rubbed at all...
the 275s cover the edge of my wheels better, I am also in an AWD so I had to match size with the front...

 

275 is a lil too wide, a 255 or 265 would be perfect

 

@IS350S2K what suspension do you have?

 

what tire brand? not all tire sizing is equal. for example a 275 toyo may run a smaller sidewall than a 275 nitto.

the best way to determine is to "simulate" the car being lowered, either by jacking the wheel upwards toward the fender, or get your heavy-set friends to help in the back seat .

 

Agreed I ran a 265/30/20 on my very first set of Work Wheels and it rubbed and I been running 255/30/20 on my last 2 Vossen wheels with no rub

 

its definitely gonna rub.
