need a little help with off road tyre choice

im looking to get a set off off road mud tyres 20% on road 80% off road. now i have a spare set off standard land rover discovery 1 alloys. the question i have is how wide can i go on those alloys, the tyre size ive been looking at is 235 85 r16 but could i go to a 245 or even a 255 85 r16. i know the rule of thumb is skinnyer tyres are better for mud but im not all ways in the mud and more tyre on the floor means more traction. please advise thank u

mmmmmmmmm, thats not been asked before, if only there was a search function!

Broader tyres use more fuel. Larger diameter tyres may well need a springs change and or a bodywork cut.

If the majority of your work is onroad, I suggest you go for 235/70/16 or 255/65/16. Go for BFG AT or GG AT.

ive got a 2" inch spring and shock lift and im not worryed about the arches a lump hammer will sort that out all im worryed about is tyre size choice and one thing i 4 got to add wot tyres are werth buying im not looking to spend stupid money like 200 - 300

tis bollix

tis not

bigger IS better

on a serious note... 2-300 for a set of mud terrains?

There's tyre's on the market for £200 each!!!
If your buying second hand you might get some sorta half worn but if your buying new i'd at least double your budget!

My view on tyres depends on what I actually do offroad ..

I mostly greenlane with only a few Pay 'n plays, so an AT tread is good for me, there's always a lot of roadwork with green-laning in UK, so something like the Insa's would probably wear quickly. If I mostly went PnPing then I would choose Insa, or other Mud-Tyre so I could play harder ..

Size doesn't matter to me too much other than I wanted larger diameter, so went 31x10.5x15 BFG AT .. a great compromise tyre for on and (mostly greenlane) offroading. Seriously thinking of trying 33" next though ..

What I have found is that if I sell them at about 25k miles there's still masses of tread on them, but the edges are getting rounded so offroading is compromised a lot, but they'll still fetch £250 a set on ebay, which offsets the full cost of new ones!

If you are talking wider, and talking proper mud then no it's not.

I asked him whether whether it was per tyre or for a set because I don't think his budget was realistic either.

i'm jesting

my mate had a rrc with 310 width tyres on and it wasn't that good... just kinda aquaplanned across mud if that made sense... only thing they were good for was bridging deep ruts!

think the widest i'd go on my disco is 285 but then it my daily driver as well as a toy so a compromise has to be made, when I can afford to insure two cars realistically I'm sure I'll get myself a little diesel run about and then I could afford to go a bit more balls out with the disco...

If you are talking about a daily driver bear in mind that wider tyres use more fuel - fact. It's all to do with rolling resistance.

They may be thought of as "big and butch" but they will hit your pocket.

yea i've thought about tyres quite a bit and once the boot floors been replaced it'll probably be my first investment... i think i'll be sticking with my normal road tyres or some reasonable a/t's if i pick a cheapish set up and will store a second set of wheels and m/t tyres for off roading... all depends on budget though, for what I do a decent set of a/t's will suffice for green laning and work although an investment in chunky m/t's would be nice if I start getting into pay n play sites and heavier off roading...

Partly why I stuck at 10.5 wide (slightly less than 285, equivalent to 265ish) .. but also 'cos they're easily found at that size, more are made and they're a bit cheaper ..

I think the rolling resistance between wider tyres really doesn't amount to feck all in mpg when you're pushing a 2 ton brick through the air ..

I agree, I'm in two minds as to what to do... i don't particuarly wanna run M/T's when i'm doing 1000 miles a month on average... the enduro's h/t's that were on it when i got the disco have done pretty well, they coped at salisbury plains and they've coped at work fine, they're also pretty much faultless on the road and cheap to replace (my local part worn place got the last one i needed in nearly new @ £35) but i'm concerned they're gonna struggle with towing c*** round sites and driving across loose ground/wet grass in the winter...

Well all I can tell you is that the difference between 235/70/16 & 255/55/18 was very noticeable (on my TD5 auto) in terms of mpg and responsiveness. There was noticeable less drag with the slimmer tyres.
