Fitting AT’s

[Lesgrandepotato]

I’ve got my jeep recently, it’s WK overland. So it’s running the 245/60r18’s they are due replacement and I’d like a bit more chunk.

There doesn’t seem to be much in that size… discoverer ATT’s seem the best of the bunch.

Will I get much more choice / tyre performance dropping down to 17rim and going something like 245/70r17 then I could get some BFG’s or discoverer AT3’s?

Will make any material different. Not doing anyhttserious just the odd trial event.

So shifting up to 255/60 r18 shouldn’t be an issue then? and gives a bit more option? Any insurance implications? Or is it a supported size for the vehicle / rim size?
