rrr47 Posted May 23, 2015 Share Posted May 23, 2015 I have a Range Rover Classic 1993 with the LSD mounted in the transfer box, (auto locking diff some may call it), can I run different tyre sizes on each axle? 235/70 x 16 fronts, 255/70 x 16 rears? Will the LSD get confused and think the one axle is spinning? Any help/advice much appreciated. Quote Link to comment Share on other sites More sharing options...
mad_pete Posted May 24, 2015 Share Posted May 24, 2015 I personally wouldn't. In theory it could make the diff always engage. I think 4 wd systems should all be the same size. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted May 24, 2015 Share Posted May 24, 2015 You should only run all the same size tyres on all land rovers. Personally I run all the same size and the same make/type. Failure to do so will at best result in massive wear at worse a broken transfer box. Mike Quote Link to comment Share on other sites More sharing options...
robertspark Posted May 24, 2015 Share Posted May 24, 2015 http://tire-size-conversion.com/tyre-size-calculator/ Use the comparison tool here Basically there is a 4% difference which is not good add to that the front to rear wheel speed variance when turning a corner and the difference will be greater Not a good idea in short If you really want different size wheels try for something with a closer circumference Would not recommend this at all on a standard landrover centre diff or the bronze / copper washers behind the centre diff gears won't last too long in my opinion With an atb the gears may be forced into the pockets (locked application / locking using friction between the helical gears and the pocket recesses) more often so I guess over time the effectiveness of the atb may diminish) Ian ashcroft should hopefully be along shortly (maybe next working week) to offer a yoda insight. Or you could give him a bell for a chat If you have abs on your vehicle there is an allowable rolling circumference difference before that goes haywire. Do a search for wabco habs d series manual I posted a few links to it on here regarding 3 amegoes etc (can't spell) Rob Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted May 24, 2015 Share Posted May 24, 2015 ^^+1 ...what rob says. VERY bad idea to run differing F + R tyres on a RR Quote Link to comment Share on other sites More sharing options...
rrr47 Posted May 24, 2015 Author Share Posted May 24, 2015 Thanks for all the input, I found two 235/70 x 16 Disco steel wheels with brand new Michelin tyres. Then two 255/70 x 16 tyres the same make and pattern, one on a steel Disco wheel, one wheeless, again brand new. All were very cheap. Now I will either have to find two other 235s or 255s.
