Can I upgrade to wider tires?

Hi all,

My current wheels are the porsche 19" turbo twists (19 x 11 - 64 ET) and I have 275/30/19's on the rears. The tires look really narrow and look actually narrower than the rim itself. Anyway, turns out that my rears have been underinflated for quite a while and I inflated them last week. A day later, I noticed two fat bulges on the inside sidewall of the rears. So to make a long story short, I need to swap them out.

I'd like to go with 295/30/19 Bridgestone Potenza RE050A Pole Position tires.

The question is whether or not I'll have any issues fitting bigger tires on this wheel. I really want to avoid any rubbing or really bad handling.

I would say the that 275 was too small of a tyre since I am running that size on my 19x10's and they fit perfectly.

You should have no problem with 295 and maybe 305 or 315 but is this on a NB or WB? If NB then with the 305 or 315 you might have clearance issues.

BTW...your first thread/post and we don't even know you here on the 6speed ???

Please post pics and details of you car ASAP then we can assist better.

Thanks

newport996 I knew you would help out here since I knew you had 11's in the back, but I could not remember the size of the tyre you use.

Have a look on tirerack.com, under the specs for each of the tires, the tables show what range of rim widths the tires will fit on. Some 275/40/19 tires will fit an 11" rim but most with a smaller aspect wont.

I run 11.5 on the rears with my 18s on 295s. Just had to roll my fenders just to make sure they wont rub

we have 275/30/19's on our 996 as well, that are offsets from the fronts. there was no rubbing on ours, but we decided for aesthetic purposes to place 7 mm spacers to bump out the look a bit. it helped a bit and did not seem to alter the handling. we are wide body style wannabe's! =)
