21" tire options?

SWOT1 · 10-23-2018, 12:46 AM

Looking to go a little wider on the 21" wheels and having already experienced 3 flats within the 1st 8000 miles, want to stay with run flats or self-sealing rubber. Are there any other options besides CONTISPORTCONTACT 5 CONTISEAL, if I should want to go 255 40 21 and 285 35 21 rear?? (and if I stay stock at 245/275's, best run flats?)

I asked the same question on here.

The concensus was, it’s a No.

It also may not help should you need the warranty.
