haha, it's so much harder to find some decent tyres for 17" all the ones i seem to find are like £100+ and i need 5 so they're all matching. Having a nightmare.
Mine are 18" off a jeep. Even less choice but cos I've got 2" lift etc I got them in with some trimming of arches etc. I did have 16" black steel modulars. With 16s there loads of choice Bfg AT's are very good think 215/70/16
Im in the same boat, though im halfway through swapping onto winter tyres currently.
Im tempted to keep the 17s for road use then if I want to get dirty, swap over to a set of 16s
As an aside - brilliant forum, with a wealth of info available on search (Ive lost many an hour going through, what tyres, IRD and VCU issues LOL)
