    235/85/16 vs 245/75/16

    Hi All,

    So I've had standard size tyres 235/70/16s, 225/75/16's and now 235/85/16s on my Disco.

    Shes nearly read for new boots.

    Considering 245/75/16s this time but been happy with 235/85/16's so tempted to stick with them.

    Obviously Ill retain better clearance with 235's but possibly better on road handling with a 245?

    Is there anyone whom has run both over the years and has useful feedback on your thoughts for each case 235/85 vs 245/75? on road and off?

    Thanks,
    Rez

    Question

    How were the taller boots off & on road? Oh & what were they, i.e. muddies, A/T's? did you need the "camel cut"?
    Just asking as am tempted to get taller 235's, thanks

    I went from 235/70/16 ATs to 245/75/16 MTRs. Had to adjust the steering to stop them rubbing by limiting how far the wheels could turn, which was an easy job once I figured out how to do it.
    I've been told the better size for a D1 is 245/70/16. I think that was actually fitted to some American D1s, but I could be wrong.
    My D1 has a 50mm lift, but the wheel arches have not been trimmed.
    You can certainly feel that the vehicle has larger, wider tyres and is sitting higher. On the road the larger MTRs are noisier than the smaller BFG ATs were. Off road, its a big improvement, so it's a trade-off.
    Hope that helps.

    I've had both on my disco and the preference is for 245/75/16, I only tested the 235/85/16 for a couple weeks when I got my 110

    I have a 300tdi manual and found the extra height of the 235/85/r16 too sluggish to the point where it was annoying taking off.

    I've driven a v8 auto and that copped with the extra height much better and I think a 300tdi auto would be ok as well

    I've got a camel cut and a sagged +2 lift

    245/70's should have been the standard size as they are near enough perfect for a D1, i prefer 265/70's on my tdi auto bar the speedo correction required.

    On our '98 Tdi with 2" suspension lift we have 245/70 Bridgestone A/T's, nearly due for new boots, still working through what to buy but love the look of BFG M/T.
    Have had no clearance issues in some pretty articulated suspension situations.
    Engine performance is still ok with presumably moderate rolling diameter increase.

    I have 245/75's on at the moment, which put the speedo spot on, and don't seem to make the take off too painfull with a manual gearbox, I am actually tempted to try 235/85's next time, think the narrower profile might be better.

    good question, keeping an eye on peoples replies

    I like my 245/75/16's on the disco. Little extra height and just a little wider which I prefer. However it puts my speedo out about 5ish %. Not a huge problem, just means I have to remember to take that into account when calculating my fuel economy figures.

    Also, as far as I'm aware, there are more options in tyres for the 245's and usually a little easier to source.

    Are you sure its out, most here with 245/70 or 245/75 find that the speedo is now spot on. When i have the 265/70's on its about 5% under reading.

    Hi Chris,
    I think you are confusing your speedometer with your odometer.
    I find that on original tyres Speedometer is approx 7% optimistic however Odometer is accurate.
    Your tyres would change this by approx 5%, hence your Speedometer would now be approx 2% optimistic however your your Odometer would under read by approx 5%. It is this 5% you would need to take into account when calculating mileage even though your speedo is pretty close to the mark.
    I hope this makes sense.
