Oh righto...I wrongly assumed 285 because more rubber on the mud? Sounds like im wrong again! Would 285 catch the wheelarch on lock?

265 is the widest you can go without spacers / adjustments iirc.
235's on mine, can't complain.

285s on mine. They will work with Boosts although a wider rim is recommended,and unless you fit 30mm spacers (or use wheels with 0 offset) your turning circle will be spectacular! You will also get crud all over the outside of the vehicle (inside too if the windows are open) unless you fit some form of mudflap adaptor. They look great, however!

Popular choices are 235/85, 265/75, both of which cause no issues, or 285/75. Any larger and you'll need suspension mods.

265 is the largest you can go without causing any issues, larger either mucks up your turning circle requiring spacers, which then results in steering shimmy, and horrible feedback through the steering when you hit bumps etc.

Personally having over 41 years experience of LR and RR's I would not go any larger than 265 or 255's at a push. 255's raise your gearing, and depending on your engine and power output can absolutely kill it - trust me I learned the hard way - larger diameter tyres can make 0-60 never happen...

Thanks for all the advice. Think i will go 265 by the sound of it is the safest maximum bet. Cheers.

In my opinion I would fit 30mm spacers also, I've not found that good quality hubcentric types introduce any steering problems but they do allow you to wind in the steering lock stops a fair amount giving you back a just about reasonable turning circle. 265/75 and 30mm spacers just allow the tyres to be covered by the bodywork.

I run 305s (305/70/16) on ET0 offset wheels and have a much better turning circle than standard as a result.
They are the same height as 255's but 50mm wider Smile

Motor chipped so no problem with 0-60 Laughing

It's actually almost the opposite to that.
Width gives you floatation (which can be a good thing if that's what you want), contact *length* gives you traction. Therefore the taller the tyre the more traction, and if you've got the same area in contact with the ground the wider tyre will have less length on the ground.

Edit: 235/85 R16 is standard fit to Boosts, 255/85 is wider and taller, 265/75 is the about same height but wider, 285/75 is about the same height as a 255/85 but wider.

A fellow forum member sent me a photo from your gallery as the recent wheel purchase of mine are exactly the same as yours. I too was considering 305's. For peace and quiet though I think I am leaning towards the 295 ATs instead of MTs?

Nice looking setup......
