According to tire calculators on the web, 285/40-20 has the same overall diameter as the OE staggered rear 255/45-20 size. Anyone try this size on stock rear SRT8 rims? Thoughts?

I just put 275/50/20's on the back, and 255/45/20s on the front.. They both fit very well

C'mon, no one has gone with 285's? It may not even be possible on the stock 9" wide wheel, but if anyone has any information it would be much appreciated.

You would have to watch the inside wall and the fender well when you hit a bump ... That would be my concern ... I know the fronts don't have much clearance on top ...

here is my car with 285/40/20's on the rear. keep in mind, i had my rear wheels widened by 1.5". i had to run a 3mm spacer due to the widening taking place all to the inside. no clearance work needed to be done to the inner fenders. i have a friend who squeezed 295/40/20's on the rear of his srt on the stock 9" wheels and has no issues with clearance. he is stock height. my car is lowered 2".

I have a stock SRT8, with stock wheels, with 285/40/20 in back and 255/45/20 up front. It rides great (they are Nitto NT420s) and they are lasting a long time (wearing slower than my factory F1s thats for sure).

No rubbing whatsoever. But I think I will go with 245/45/20 up front next time - because with the 255s, they look a little large for up front (245 was stock, remember).

dog - almost the same set up i have. i used the 245's up front due to the low ride height. i noticed the nitto 420 are wearing great also!!! i also like the fact they do not vibrate at 75-80 like the F1's did!!!! not as sticky, but for my driving habits, definately a better choice! plus the tread looks cool as hell!

 

[SRTOCHO]

what is the difference in inches between the 255's and the 285's to the ground?

 

[MR C]

can 275/50/20's fit all around ?? I mean front and back . someone post awhile back but I forgot. I think someone said they rub in reverse but I am not sure

c - i know a 275/40 will work, but not sure on the 50 series......

Wow, at first just a trickle of information, now a flood. I couldn't wait, I need new tires real bad, I was getting nervous, so yesterday I ordered Nitto 420S's in the stock staggered sizes, 245/45-20's up front and 255/45-20 in the back. SRTDogg, do you have any pics of your setup with the 285's in the back. Maybe it's not too late for me to switch on Tuesday. Thanks.

legmaker, those rears are SUPERBAD! Where did you get them widened and what did they charge?

Where are you getting the Nittos from?

thanks for the info man . I was maybe thinking about the 275 50 If I could find it in an 18 inch to give it that old school flavor .

275/50's are almost an inch taller than the stock setup!!

That is penalizing our rear gears even further...I think I would go shorter than taller if straying from the stock diameter.

I'm running 305/45 18's Nitto 555R'son the back of my car with no issues/rubbing.

Huh

18's............got any pic's

 

[SRTDogg]

Yeah Moparrbust, got any pics of your 18s? Did they clear the brakes?

SRT_er, I don't have any pics, but the 285s are 30mm wider than 255s. This equats to 3cm, which is just over 1in (2.54cm). So it would be over 1in wider in the back, per wheel. It is a big upgrade for sure.

It looks a lot meaner and much more awesome than the stock tires looked from the back, but overall I'm just mildly enthused. I was realling hoping the wider tires would set it off more, but 285 just isn't all that crazy on this large beast of a vehicle.

So now I'm waiting to get 305s, ideally, but I need to get wider wheels first.
