460 tyre size ?

Hi Cliff
I have 235 85 16 BFG all terrains on standard steels
On full lock, (in one direction only), the tyre rubs the hockey stick suspension member, ( don't know the correct name maybe a leading arm as opposed to a trailing arm). The effect is that this arm has a polished section about two inches square, other that that I am happy enough with the fit, (you quickly learn just to back off the lock a fraction. Having said that, if my steering was centred properly maybe it wouldn't rub in either direction. All in all I don't find it a problem.
BUT
If you did go for a diesel, especially the 617, it may interest you to know that I noticed a big drop in acceleration, (don't know if thats the right word), with these tyres on due higher gearing effect. It could be hard to find a 617 turbo.
I wonder if the 300 diesel of a 95 or 96 W124 can be made to fit easily. It has a multivale head which gives it 135 bhp, I think, without a turbo which might not be a bad thing power delivery wise. A big difference to the standard 617s 88bhp
