help with tires and rims

Recommended Posts

hey there everyone - In a month Im going to be the proud owner of my first Porsche! Granted, its a '99 (Boxster with 12K miles in PERFECT condition), but Im excited nonetheless.

I want to put new rims and tires on the car, but have concerns about rubbing and fit. I found a set thats reasonable and look great on ebay, but Im a total noob and all the information to calculate if they will fit is somewhat overwhelming to me (offset?!). Ive tried doing my due diligence and reading all the posts, but I still cant make heads or tails of it all.



The store selling the package has ensured me they will fit and wont rub, but therre are no returns and I dont want to make a costly mistake. Here are the specs they list which, again, mean almost nothing to me; all I now is that I love the way they look:

Wheel Diameter : 19"

Wheel Width: 8.5" Front and 10.5" Rear

Wheel Offset: ET45 Front and ET52 Rear (Boxster Fitment Available As Well)

Tire Manufacture and model: Toyo T1R

Tire Size: 235/35/19ZR Front, 275/30/19ZR Rear

Vehicle Fitment: Porsche 996, 997, Boxster

Ahead of time, thanks for all the patience and help...I really appreciate it!

19" rims on a '99 Boxster is not recommended. Can be done, with the proper off-set and/or spacers but that size rim is much larger than Porsche intended for the current wheel bearing setup. Might also compromise ride & handeling. Lastly, 19" tires are much more expensive and harder to find.

Look for 18's.

19" inch rims will give you a ride that SOME will consider too harsh. Do a little more homework and see if you can drive a Boxster w/19's, 18's. etc. and see which one suits you best.

If you want to do some useful reading about offsets, rim & tire sizes, take a look at the following link:


Good luck with your new ride!

19's couldbe a little harsh, especially riding on 30 seriese watch out for those pot holes

Those 19's U wanted won't rub but prolly will need a pair of 7mm spacers on the rear & dont worry about their no return policy.

here is a set of 18''''''''''''s I got , I think 18's looks sweet with sport or row suspension :D
