8.5" rims are mid-point in the width range for these tyres and are the width used for this tyre's section and tread width measurements.

I have since fitted a screw to the inner guard at the bulge for the fuel filler pipe as there was evidence of slight rubbing.

Hey Graeme
Basically from what I understand you're saying is my wheels shouldn't have any problem with these tyres right?

Also I don't quite understand. What have you screwed back mate?

The width of your wheels is ok for the width of tyres you want to fit .

I remember reading about what Graeme is talking about now !!
The plastic wheel arch liner has a bulge that bigger tyres sometimes hit , and it can be fastened back with a screw to move it out of the way .

I'm struggling to find a supplier for the BFG's here in Russia.

But I can find the Goodyear Wrangler Duratec in 275 55 20's. They don't seem to be as good as the BFG's but it might be the best I can get unless anybody else has some alternative suggestions



Does anybody know if they're any good?

Thanks in advance guys

I had LT245/70R17 Duratracs on my D4. I liked their excellent all-round performance but the tread was a little narrow which gave the impression of exposed sidewalls. However in 255/55R19 the tread is wider than most if not all other brands in this size and gives much better sidewall protection. I haven't seen them in the flesh in 275/55R20 so don't know if the tread is narrow or not. My BFG's tread is wide with a square edge which is excellent for sidewall protection.


I note that GG AT are available in Europe in 255/55R20 (L405 size), having the same sidewall height as the 19" and would better fit the spare wheel well.

I have 255/55R19 Goodyear Duratracs as my winter tyres and have been pleased with them. Reasonably quiet on the road, fine on ice and snow due to softer compound and reasonably open tread pattern, good on grass and mud, including towing on soft ground, OK braking and steering on road, though obviously less good than OE Continentals. They are LR homologated which should help from an insurance perspective. No experience of BFG alternative, but comparing with Goodyear MT/R which I had before, the Duratracs are much better on road and on ice and harder snow, slightly less good on mud, probably more prone to damage on rocky ground due to softer compound and less reinforced sidewalls, but that is less of an issue for me, so the Duratracs suit me much better. Only Range Rovers since 1988

Hey guys. I can also get Cooper Discoverer A/T3 275/55 R20. What would your opinions be in terms of preferences agains the duratecs?
I've not seen either of these in real life so all I can go on is the images. From this only the duratecs seem more aggressive

I know someone who liked the AT3s in 265/60R18 that he had on his D3.

I have no experience of the Coopers, but you might like to look at the "cracks in sidewalls" thread on this page and other places. Only Range Rovers since 1988

Thanks for pointing me in the direction of the thread...

...nuff said looks like I'll be opting for the Duratecs.

Can anybody tell me if the compound on the Duratecs is ok in temperatures of -30 degrees ?

I'd say the Duratrac compound is halfway between a full winter tyre and a summer all terrain, so will not give as much grip in these cold conditions, though their more open tread will help in the snow. You might like to look at Canadian or US reviews for winter performance. If your main focus is on winter road driving, then from comments I have heard, though not personal experience, a full winter tyre like the Vredestein Wintrax or Pirelli Scorpion Winter might be better (LR publish a list of homologated winter tyres, your handbook should say what they are, also searchable online). If you are doing a mix of road and off road and can accept reduced winter performance in order to have better off road grip then the Duratrac is probably better. If you look at the Edfors thread on the "My Range Rover" page, you'll see MT/Rs being replaced with winter tyres for winter in Sweden, maybe similar weather?

The winter tyres will be available in the standard 255/50R20 size - I don't know about running oversize, how much it would put your speedometer out, whether it might put more strain on the drivetrain, rubbing etc. I have spare 19" wheels for the Duratracs, so conform to standard size/homologation.

Are valenki still worn at those temperatures? Only Range Rovers since 1988

I'll be changing the car in 12 months so I'm only concerned about the rest of this winter season. So probably the Duratecs will be the best option. I understand it's always best to have separate winter and summer tyres in my conditions. I'm just trying to save a bit of cash. I need to replace my tyres so just trying to find the best set that will see me through

I presume this bulge comes down from the fuel filler? Is there enough play to be able to screw this back without affecting the fuel pipe?

I've never done it , but there is info on this thread
http://www.rangerovers.net/forum/6-range-r...tires.html

[QUOTE=fisha;333835]OK - 275/55 R20 Cooper LTZ fit on the original standard 7 spoke Vogue alloys ... just. Its very very close and the very limit of the RR's ability in stock form imho.

When I say close, its mm of clearance. Depending on the front wheelwells, I get very minor scuffing where the tyre just brushes the plastic on full lock, but on normal cornering its fine.

2 main easy 30 second mods required:
- There are little cones that protrude down from the air bag seat on the front strut. These needed trimmed with a pair of snips as the tyre is so tall. Non strutural in any manner, and just a bit of excess moulding as far as I can see.
- The fuel filler protrusion on the rear right wheel well. It needs trimmed and held inwards a little. Its non structural , and I used a self tapper that pulled the wheel well into towards the plastic guard of the tank and filed away a bit of the corner just for extra space. If you look under you'll see its pretty easy to pull it away from the corner of the tyre.

General observations on the setup.
- They look very chunky and you see other RR owners looking.
- Its a softer ride over the little bumps.
- There is a little tyre hum at speed.
- It dulls the acceleration and handling.
- It absolutely murders my mpg.

I have the old size road tyres (265/50R20 )... and am going to put them on another set of alloys for the summer as I really only bought the LTZs for the winter months and the bad weather.


Hope that helps.[/QUOTE]
