Fender liner rubbing with stock Z4M wheels and 245/40-18 Front - 275/35-18 Rear?

TRSpitfire · 03-07-2012, 02:48 AM

I'm getting ready to buy new tires and would like to go a bit wider and hopefully reduce some understeer. I've see lots of recommendations to go with 245/40-18 and 275/35-18, but also saw one post saying they rub when turning near full lock.

Would appreciate feedback as to other experience with this. I have to pull into tight parking spaces regularly, so rubbing on full lock will be an issue.

The best thing to do to reduce your understeer is change your alignment from OEM to something more aggressive. Then start thinking abour hardware upgrades.

TRSpitfire · 03-07-2012, 07:09 AM

Thanks for the great advice, and I will make sure to adjust the alignment as well. My tires are shot right now though, so need to make a decision on size...

Daemonblitz · 03-07-2012, 07:21 AM

I have those sizes on my fronts, never rubbed at full lock.
What brand tires are you looking at ?

TRSpitfire · 03-07-2012, 08:13 AM

Thanks! I'm debating between Pilot Super Sports and Hankook RS-3. Tires are crazy overpriced here, so I plan to order from Tirerack. Even with the $300-$400 shipping it will be cheaper than buying locally. I don't want to get it wrong though as it will be an expensive mistake.

Looks like you have aftermarket rims...Do you think the stock rims will be different?

FWIW, for fitment purposes only, I swapped my OE rears to the front to get an idea of how much clearance there is. I drove it around the block carefully and went full lock without problems. Then swapped back. You could to this to get an idea of clearance, but of course, don't drive like this.

This weekend after I install wheel studs, I'll post try to remember to post photos of 18x9.5+35 with 265 Star Specs for autocross. Need 5mm spacer up front so rim protector doesn't brush strut. Rear has slight rub on inside liner.

Shipkiller · 03-07-2012, 10:11 AM

My last two sets of tires came from Discount Tire. Cheaper and free shipping...

beta · 03-07-2012, 03:07 PM

245/275 PSS tires here, no rub (and i'm lowered 0.4" on coilovers).

You won't have any issues. I've had Dunlop SP 01s and currently running PS2s in those sizes on my front stock rims. The profile pic you see is with my ARC-8s which are wider than the stockies (sticking out an extra 13mm) running the same width tire as a Hankook Ventus and those don't rub either.

I put some 235/265 Pilot Super Sports on today. I've only had them on a few miles, but I can already tell you I'm extremely happy with the choice.

onelove · 03-08-2012, 09:28 AM

Pilot Super Sports are one of the best street tires I've ever driven. Great grip on the street and track, and they aren't too loud in comparison to other tires with similar grip levels.

On the 245/275 setup, the liner will eventually wear through and clearance itself in a few spots and you'll have no more rubbing, not that big a deal.

partlowr · 03-08-2012, 11:32 AM

Is your car lowered or do you plan on making any suspension changes? Ride height is going to come into play depending on how aggresive you go with your wheel and tires. Keep that in mind.

TRSpitfire · 03-08-2012, 02:34 PM

Thanks all. Currently the wheels and suspension are all stock, but I do plan to lower just a little in the near future...Will that help or hurt?

It's most likely going to hurt, 9 times out of 10 when you lower a car you loose a little clearence somewhere, this will especially be the case up front when wheels are turned, you might have full clearence with the wheels straight but rubbing when you turn to full lock or close to full lock.

I am running 245/40's in front and 265/35's in rear with H&R / Koni Sport setup. No issues at all.

E92M3Pilot · 03-11-2012, 12:35 AM

I ran 245/275. No rubbings on Stocks setup.
