darren m Posted November 12, 2010 Report Share Posted November 12, 2010 is it ok and safe to mix tyre size -- thinking larger or next size ( 265/275x70x16 ) up on back and put my 2 good back tyres ( 245 x70x16 ) on to the front. reason -- i eventually want to put bigger tyres all round but the 2 rear ones are as new and cant afford a full set .. wonder if i could run it like this for a while ? what do you think cheers ps . its on a LWB trooper by the way Quote Link to comment Share on other sites More sharing options...
al4x Posted November 12, 2010 Report Share Posted November 12, 2010 you can only do it if you only use 4x4 when its really slippery otherwise it will wind up the diff badly, though personally I wouldn't bother with the bigger tyres simply because the cost ramps up severely, look at 245 75 16's they seem to be well priced Quote Link to comment Share on other sites More sharing options...

Obviously you will will end up with more ground clearance with the larger tyres but if you are not having a problem at present then it does seems to be spending money you could use on cartridges Quote Link to comment Share on other sites More sharing options...
Hanks Posted November 12, 2010 Report Share Posted November 12, 2010 I tend to agree with al4x. Obviously you will will end up with more ground clearance with the larger tyres but if you are not having a problem at present then it does seems to be spending money you could use on cartridges Your speedo will be reading lower by about 5% but the main issue here is you have to put the same size tyres on a 4x4 otherwise the smaller diameter tyres will be going round quicker than the others and this will cause the transmission to wind up under strain and either the half shafts or the diffs will break. I would even go as far as to say you should not only fit the same size but also the same manufacturer and tyre type to ensure the tyre's circumference is the same.

gsm1968 Posted November 12, 2010 Report Share Posted November 12, 2010 I think we need someone in the tyre industry to answer here. The tyre sizes the OP has quoted are only diferent on the width. The profile and rim size are the same. I would see no problem with that. Although going wider is a waste IMO. Looking forward to a reply from some one in the know Quote Link to comment Share on other sites More sharing options...
al4x Posted November 12, 2010 Report Share Posted November 12, 2010 the profile is a percentage of the width so the wider they are the higher the sidewall is. This is on a 4x4 that isn't full time 4x4 so odds are you would get away with it but when you engage 4x4 unless its very slippery you will wind the diff up Quote Link to comment Share on other sites More sharing options...
darren m Posted November 13, 2010 Author Report Share Posted November 13, 2010 right i,m confused - which size is it that means the tyre hight , not width , my width is ok just wanted a little hight cheers Quote Link to comment Share on other sites More sharing options...
Moors Man Posted November 15, 2010 Report Share Posted November 15, 2010 (edited) with a size 245/70 x 16 The 245 relates to the width of the tyres, the 70 relates to the hight of the rubber itself (70% of the 245 width). The 16 relates to the size of the wheels themselves. Edited November 15, 2010 by Moors Man Quote Link to comment Share on other sites More sharing options...
al4x Posted November 15, 2010 Report Share Posted November 15, 2010 right i,m confused - which size is it that means the tyre hight , not width , my width is ok just wanted a little hight cheers ok keeping the profile the same and getting a wider tyre (the 265 figure) will raise the truck but also going up to a 75 profile with the original width will do the same, with two tyres 265/70/16 and 245/75/16 there is next to no difference in height in your case just get 245/75/16 and you will gain a bit of ground clearance Quote Link to comment Share on other sites More sharing options...
luvbus Posted November 15, 2010 Report Share Posted November 15, 2010 Axle wind up aside, if your Trooper has ABS fitted you should not install tires with different rolling diameters as it may interfere with your brakes! Quote Link to comment Share on other sites More sharing options...
