Hi Guys,

I just picked up a 996TT last weekend. My friend offered to sell me his BBS LM's from his 996 C2 for a ridiculous price. I bit and bought the wheels from him. The front's are 235/35/19 and the rear's are 275/35/19. The rear wheel is 10" as opposed to the stock 11" wheel width. Is that going to be an issue? Can I just change the 275's on the rear wheel to 295's and the 235's to 225's to retain the stock tire width's? What are the effects of running improperly sized tire ratios? I've been reading on the forums and that seems to be a huge no-no.

Thanks

 

Wheel spacers in the back may be needed to fill things out. I'm sure others will chime in on the tires also.

 

Well, you should have posted this ?? before pulling the trigger no? LOL...

The bummer is that you went from an 11" to a 10", depending on the off-set you have on the BBS will determine the spacer kit you'll need for the rear, I would estimate 17mm - 25mm might help to push the wheels out a bit.

The fronts should be fine, I'm sure around 45et....

The tires in front are fine at 235/35/19, the rears are an other issue as in order to maintain something close to factory you'll need a 275/30/19 or 305/25/19 or 315/25/19 for your specific vehicle.... Now we all know that getting a 305/25/19 or 315/25/19 to fit a 10" wheel is going to be HARD!!! You cannot use a 295 since you went to 19", it would cause you to gain an full-inch and that cannot be good...

If you have other questions you can call me or PM me for help....

You may need to get a set of spacers for the rear and stick with the 275's.....

Running 275 rears on a turbo is a bad idea. Yea the spacer will make it look better, but dos nothing to address the traction and safety issues.

 

Might be better to sell the wheels to a NB 996 owner and use the money made to pick up another set. it's not worth possibly blowing your front differential

I wouldnt put 10" wide wheels on the back unless its for snow tires

 

hmm....not to use a 295 huh I think I may have a problem then.. I have 235/35/19 fronts, and a 295/30/19's on 19x11 rear wheels is this bad?? if so LMK

 

sell the wheels ..... if you're doing 19 inch wheels stay with 315/25/19 in the back. do a search and you'll see how there are very few if any options.

 

Thanks for the info guys! I got a great deal on the rims with tires. $1600. I'll probably just sell the rear's and get 19x11's. What offset should I get so I won't have to use spacers?

 

you might try to get a set of barrels for the rears that work with the proper offset and width.

 

Your tires ARE NOT MATCHED IN DIAMETER for a AWD 996 Turbo.

The fronts are 25.5", the rears are 26.6:- these will destroy your differential.

If the rears were 275/30-19 you would be OK (a5 25.6")...well, they'd be too skinny, but atleast not damaging.

And why the 19" rim? Performance is lowered.

Welcome!

as already recommended. sell and get an appropriate set for your Turbo. u probably got excited when you saw the BBS wheels, don't blame u, but no sense in trying to make them work on your car.

 

If he's really your friend:
1. He would take the wheels back
2. He shouldn't of sold you wheels in the first place

 

If I remember correctly, the closest size is 19x11 +50

I would run a 15mm spacer with that set up.

 

you can get new barrels too
