[AC Ventura]

In the UK we use 225/65/70 R15 Avon CR6 ZZ. Nice high profile and same diameter as the 275/55's on the back. My application is an Autokraft Mk IV. No rubbing issues at all, but obviously depends on offset and your cars clearance.
It's simple enough to find the width and diameters of your existing and proposed tyres. Then make thin wood template and run it around the tyre at full lock. You'll soon see if there's any fouling issues. That's exactly what I did.
