an H&R spring lowered 996 turbo??? Has anybody tried this tire??? I have 235/35/19's on 542 HRE's with an aggressive positive offset. The 235/35/19's are very close to not clearing. I'm running 315/25/19's on the rear but want to change up to 235/40/19's and 305/30/19's rear which are the same run out of .1 in size to the original 18's that were stock on the car. I want a little more sidewall for better everyday driving and I can also run the new Pilot Sport tires. I need to know if these will clear. Anybody???

 

Too many variables that you have in the equation
"Lowered Suspension" ?
What are the exact wheel sizes you are running and exact offsets ?
Spacers currently or not ?
Fenders rolled ?
What is the goal ?
Street driving only ?
Be very careful if things are already close to rubbing
Good luck !

 

nope wont fit.
235 35 19 and 305 30 19 is the way to go. 235 40 19 will not only rub, it will look silly. you can do a 245 35 19 instead. that will give you a little more sidewall

 

Thanks Steve, great advice! It looks like you are running the same wheel on your car???

 

yes sir !

i used a variety of tire sizes.. the ideal set up (in my opinion) is a 305 30 19 and a 245 35 19.

 

Steve, are you running lowering springs as well???

 

i am on coilovers.
totally slammed.
i am the last owner of this vehicle.

 

How long/many miles have you put on your AWD vehicle w/this tire combo???

 

I had a set of 305/30/19's mounted up over the weekend and just ordered a set of 245/35/19's this morning. Thanks Steve ~ Blessings!

 

enjoy them ! you're gonna love the extra bite up front.

 

Don't you want the same diameter front and back tire for the AWD system?

 

I spent most of the evening yesterday reading over the 16 page link on the 6'r regarding tire size for the 996 turbo. My Michelin PS2 tire combo of 245/35/19 & 305/30/19 is .5 in size difference between the front and rear and .1 over the factory Porsche spec for the factory 18's. The difference between the front and rear are 19 revolutions per mile so they are under the 21 revs per mile max Porsche spec. This tells me they should work fine. I really hate to have to give up my 235/35/19's as they are almost new and look really good as the cars sits perfect with them.

 

From what I understand it is not so bad if the rears are taller. The AWD will just not detect spin as fast.

Its when the rears are spinning faster than the fronts that the viscous coupling can get damaged because it heats up too much due to the fact that it always thinks the rears are slipping. At least I think that is what I read. lol

 

Yep that is kind of what I gathered from the info myself. I was running the 235/35/19 & 315/25/19 combo but the ride was a bite harsh and the tires would rub every once in a while even with rolled wheel wells as the HRE's have a very aggressive positive offset. The sidewalls always bothered me being so short. I had a buddy in his 996 hit a railroad track "at speed" and blew all four 19's off the wheels. He damaged two wheels and all four tires. That's the kind of thing that happens when you don't know the area!?

The car rides much better on the 305's and I believe it will even be better once I get the 245/35's on the front.

 

And other stuff... ie:
