Can everyone please recommend a larger tire size for my Discovery 5? It currently has 255/55R20 and I would like to get bigger AT tires but I cannot add a lift. Any recommendations on tires would be a bonus.

Thank you!

you might be able to get away with a 245/60-20 (31.6") or 275/55-20 (31.9")

With a lift you can go max 285 50 20

I plan to fit 275/55-20's to my vehicle. Lots of choices in that size. Here are the ones I would consider:

Continental TerrainContact A/T - aramid fiber armored
Goodyear Wrangler All-Terrain Adventure - Kevlar-armored, have run these offroad a lot and they are awesome
Hankook Dynapro AT-M
BFG All-Terrain T/A KO2 - these don't last all that long on heavy vehicles, but they're great off-road and they're three-peak mountain/snowflake rated, and they're supposedly not terrible all-seasons.
Nitto Terra Grappler G2
Nokian Rotiiva AT - new tire, but Nokian makes excellent winter tires.

SafariDave, are you meaning to say WITHOUT a lift that the maximum size would be 285/55/20? Do you have experience or knowledge that this is accurate or are you making any assumptions? Thank you.

I’m sorry but I don’t understand why some of you says that to go 285/50R20 a lift is needed, from factory you can go 285/40R22 that has the same dimensions.

Do you have the Capability Package (i.e., with air suspension)? If so, the lowered setting might not have sufficient clearance for larger tires.

I'd strongly rercommend to not play with different dimension tyres than those recommended by the vehicle's manufacturer on any vehicle with such complex electronic managements... all those systems were calibrated from factory for standard dimension tyres and exceeding that will mix up the whole management and nothing will work 100% OK anymore, you might gain ONLY few inches of ground clearance and ruin other more important capabilities of the vehicle which will be just a bit taller but less responsive ... that's a fact

If that were true then there would be appropriate warnings in the Land Rover owners manual, and Land Rover dealers in America wouldn't be routinely performing suspension lifts and installing larger tyres. Is it possible that Land Rover computers can be reprogrammed to accommodate vehicle configuration changes, as is the case with other vehicles sold here?

It is true and tested live, the breaking distance, consumption and EGT level is increased with a similar percentage like the differnece in the tyre's dimensions while the TC and other dynamic systems are less responsive, engine temps are rising as well

if you read the whole workshop(not only owner's) manual and you'll understand how the managements are working you'll find more warnings about messing with tyre dimensions even with pressures

For me the fact that owners have fitted larger tyres and nothing bad happened SO FAR it's not an evidence that it's OK

about LR dealers who are fitting lift kits and larger tyres i can't comment....


as about owner's handbook, maybe you didnt read it carefully, IMO there are appropriate warnings, here is from the D4 one cos that's what i had saved but i checked and for D3 is exactly the same(copy/paste) warning, the only difference is the 8.5J tyres which are only for D4 (the red line is made by me)

The new Discovery with the capability package is more off-road capable than any other land Rover or Range Rover sold in America, but the stock tires are not optimum for off road excursions. The increased capability that comes with more off-road suitable tires is worth the small sacrifice in fuel economy. The other adverse effects you cite are so insignificant as to not even be noticeable. If I'd wanted an everyday SUV for on-road use only, I could have gotten one for less than half the price of the Discovery.

Someone better warn Land Rover the Discovery 5 SVX is coming from the factory with nearly 32" tires.

Lifting a D5 and putting some slightly larger tires isn't that big of a deal. Ford Explorers have no issue with it :D

I didnt say to not put off-road suitable tyres i said it's not good to put larger ones(which for me means bigger diameter) and that LR made warnings against that... IMO any Discovery is more capable off-road with standard dimension tyres while all it's enhancements are working at 100% capacity and that few inches of extra ground clearance are neglectable with unneeded adverse effects.... though if you wanted an off-road vehicle which is far better than the Discovery for that and no need to think about tyre dimensions as it has them big from factory you could have bought it for half the price of a it as well :)
... imported from Russia :devil

I installed the Good year Duratracs in 275/55r20s in October. They have worked well. Fuel mileage dropped, but that is also due to it being cold in MN.

That is the size I am looking at. Just to clarify; did you install them without any lift or other modification? Also, assuming you have a full-size spare, did it fit as well? Thanks so much.

I have 275/55-20 Cooper Discoverer AT3 and there's absolutely no rubbing or any other issues aside from reduced fuel economy. Ride is superb even with slightly greater unsprung weight.

Many others have fitted that size as well - lots of selection in that size.

Full size spare fits fine. No lift. Have had it off-road in Super Extended Mode even.

What does increased fuel consumption mean for an engine? AFAIK it means that it's working harder or overfuelling for some reason... and that means shorter life too, IMO not a good deal for some inches of extra ground clearance or a "macho" look, i'm just trying to warn everybody about something i deeply studied and tested not to start a debate, the fact that many people does it without really knowing the implications or lack of care is not valid argument ... though for somebody who doesnt want to keep the vehicle for many years that's certainly not an issue.... bad luck for the man who will buy it thinking that let's say 150.000 Km is not much but that engine and transmission will be well "tenderised" untill then. Only time will tell :)
