Largest Wheel for 986
I have searched the forum, but haven't been able to find a thread that answers my question.
What is the largest diameter wheel that will fit on the front of an '01 986 without contacting the strut/coil? A 245/35ZR 19 on an 8J x 19H2 ET57 rim doesn't fit. Based on the tire specs, the diameter is 25.9". Would a 235/35ZR 19 with a diameter of 25.5" work? |
Your question begs some questions.... I'm sure you mean largest diameter tire.
Assuming you've got 'stock' suspension when you say "hit the strut and coils", you're referring to the underside of the spring plates the coils sit on, right? It's hard to say for one thing because one side may squeeze in there and the other not. I've had 17" rims with just slightly too tall a tire (Victoracers)and it worked on the right, but not the left. I was able to 'mitigate' the rub by putting on 7mm spacers and with the angle of the strut to the hub/bearing carrier, it just cleared - luckily. If it rubs underneath, you may be able to 'shave' the tires about 4/32 or 1/8" - they'll perform slightly better too. 25.5" might work. good luck, kj |

Largest Wheel for 986
The wheels are 19" Sport Design. As mentioned in the initial post the issue I have is with the front wheel/tire. The specs on the wheel are 8J x 19H2 ET 57. The tire is a Bridgestone Potenza RE050 Pole Position - 245/35Z 19.
I have stock suspension on my '01S. I'm trying to determine what is the largest tire diameter that will fit on the boxster without using spacers with the current suspension. Thanks for your help. |
A 225/35/19 or a 255/30/19 will give you proper OD of 25". You will probably need a 5-7mm spacer for the 255s. The 255s really need a 9" wide wheel also.
You want a taller wheel up front so your Porsche will sit higher?? Rally car?? |

p.s. Just off the cuff, if you are currently running a 245/35 up front, it would seem to me that you would have to come down to a 30 profile in order to stay within an acceptable diameter. |
To answer your questions:
1) When I'm referring to tire diameter, I mean the OD of the tire. 2) The tire size is larger than the recommended Porsche standard which would have 235/35 for this wheel. But, these were originally purchased for an '06 Cayman from a local Porsche dealership. I'm taking the car to my local shop to see what options I have. Thanks, |
It sure sounds like the fitment problem you're having is due width, not height. A .4" difference in diameter ( .2" radius ) is a 1.5% change, well within the allowed 3%.
As I mentioned in your other thread, Instead of buying expensive new tires, try a small spacer, 5-7mm ( with longer bolts ). That will either eliminate your rub, or cause the outside to rub, In which case you'll have to go to either a 235/35-19 ( factory 987 size ) or 225. The 8" wheel is within the recommended range for a 245 tire. |
