Order 245/35/19 Tires having second thoughts, enough rim protection?

Ordered some Avant Garde M5 Reps and 245/35/19 tires, having second thoughts, you guys with 19" wheels on 245/35 do you feel like it provides enough wheel protection or do you wish you went with a bigger sidewall?

I'm about to upgrade to 255/35/19 and everything I've read/heard leads me to believe that it's plenty of sidewall. I live on some of the *worst* roads in the nation while you live in Florida...you'll be fine. Do yourself a favor and don't go RF, should negate some of the harshness.

BTW, sweet rims

Yea the roads in florida are actually really nice compared to most places in the country I've been to. 255/35/19 in the front? is that gonna fit? I went 245/35/19 thinking that was close to the max for the front and closest to oem diameter? And yea I didn't go run flat I went with General G-Max AS-03 I got them at a STEAL i couldn't pass up.

What type of lip does the new rim have? Post a pic. If the tires ordered have a rim protector band, you should be OK. Not all tires are designed same, and I've found Michelin has excellent rim protector bands. That's been my experience. That said your 245/35 tires will have a short sidewall, so even with a rim protector band you won't be able to rub much before scraping.

Just be careful when parking next to curbs. Learn corners of your car or back into corner spots where you can use rear view mirrors to guide.

And, don't give it to valet!

Yea No Valet!

I'll be extra careful.



What type of rim protector do these have? I don't even know what to look for?

General G-Max AS-03

Here's a shot of the tires:

Sorry, I should have mentioned it, but this is for my 2013 S4. It can run wider tires.

Nice wheels. rim protector on those tires looks decent, but that wheel lip may make it difficult for the tire to provide much protection.

BTW, that tread style looks like it may be noisy on our many coral infused South Florida roads.

Yea, I never calculated something like the coral infused roads, what tread styles are good for such roads?

How wide are the wheels? Oem 19" are 8.5" wide and have a 255/35 profile. In your case, if the wheel is wider than 8,5" i believe the tyre will stretch. Your OBC will show incorrect mileage info meaning all data will be off (mileage, speed, service info etc etc).

But they look good

Well based on tire calculators online, the difference was like .44, so there should be almost nothing in terms of mileage/speed differences.

I was rolling the 19's on my 2011 335is, and that was a mistake. They were the stock run flats, and I ended up cracking both rear rims in day-to-day driving on California's crappy roads. The rear tires were 255/30's.

I went with the 18's this time around. The stance is not as aggressive, but I'm OK with that compromise.

I had the 19's on my 335is as well with 30% aspect ratio tires and didn't get any damage to my rims on our crappy Phoenix roads but it only takes one pot hole. I purchased the tire/wheel protection warranty when I leased that one and the new one *just in case* though.

Yes, but thats only comparing the tyre profile but you have to factor the wheel width. 0.44 is ok on the same wheel (8.5") but if its a 9.5" wide wheel then you get a bigger difference as the 245 tyre will stretch more meaning lower side wall. Even with 255 you might get a too low profile. You follow?
