these days it is trendy to stretch tyres onto a rim, so we could get them on their, but to be frank the tyre wouldn't be working at it's best. the shoulders of the tyres will have to work extra hard, and the tyres won't be protecting the wheel the way it should. So if you want to stick to 6" rims then a 185/70 will suit thos e wheels better.
However if you come and see us we can put a 165 on and you can have a look
Thanks Dougal I'll bring the Momo's up in my DD at the end of the year and we can see how they fit, personally I hate the look of stretched tyres....
I've already altered my balance by removing the rear ARB and fitting a stiffer front, definitely improves things and might be why higher front pressures don't work for me, at the end of the day its all about whats best for you and the car really, whatever pressure goes where ..
