as this questions has never been asked before
as this questions has never been asked before Whistle ....

What is the biggest / widest tyre i can get away with on standard 16 inch boost alloys for my 110. As i really would like them to fill the arch out better for that "complete" look. Twisted Evil

Im guessing they have got to be Mud tyres, i see a lot of "western power" 110's with monster tyres on and fancy a set soon..

All coments welcome even those telling me to do a proper search you Pen...Is.

Ben

285 is generally accepted to be the widest tyre you can safely put an a standard Boost, but the advice from BF Goodrich is don't go wider than 265.

I, and many others here run 285/75x16 tyres (in my case KM2s) and have done hundreds of thousands of miles on them with no problems. If you do fit 285s on Boosts you'll probably want 30mm spacers as well.

If going bigger than recommended size (265..?), I'd make sure the insurance company is OK with that. They'll use any excuse not to pay out.. Evil or Very Mad

Go for taller rather than wider, body lift without suspension adjustment. BFG do 255/85 MTs (as do Toyo in their Open Country range) Land Rover Defenders. 67 years heritage, minimal appearance changes, still going strong all over the world. Not a fashion vehicle, but fashionable to own. Made for the needy, not the greedy. Ta ta Defender

255 makes little difference for either. See this for comparison http://www.kouki.co.uk/utilities/visual-tyre-size-calculator

I use wheel spacers anyway so can't comment on turning circle differences. My 255s don't look that much wider than 235s, though the latter were on 17" (I think) standard boost alloys & former on steel 16". Land Rover Defenders. 67 years heritage, minimal appearance changes, still going strong all over the world.

Spacer attaches to hub, wheel attaches to spacer, effect is to move the wheel outwards by the thickness of the spacer (same effect as changing the offset of the wheel).

With wider tyres they allow the same angularity on full lock and hence maintain the turning circle.
