I run Toyo 275/55 r20 with no rubbing at stock height, but on Redbourne wheels... There is a small offset difference.

 

I've never run the AT Revo 3s so I can't compare them to the Toyos. I don't think they are 3-peak rated though. I will say that I do not find the Toyos to be noisy. I do think they might be a tiny bit noisier than the Good Year Adventures, but that's with me really having to work to pay attention to it. The Good Years were very quiet.

 

I plan to replace the OEM tires with BFG KO2 or Cooper AT3 4S but unsure which snow chains would fit perfectly. Did anyone have already experience with snow chains on 275/55 R 20 on standard rim?

 

If I needed to put snow chains on a winter rated AT tire on an AWD vehicle, I would just pull over until the snow plow got there.

 

Point is that in some areas of German, Austria, Switzerland, Italy and a few more you need to use snow chains. There exists a traffic sign and you need to put chains on - independent if you have an AWD vehicle or not. If you move on without chains and they catch you, you have to pay a penalty. That's why I'm looking for snow chains which will work. I found a few fitting the size - was just asking if someone has good or bad experiences made already.

 

I'm interested in hearing how well snow chains fit the Defender with 275/55/20 tires. I am running that size myself. Because it is slightly wider than the OE size, there may be an issue. LR official policy on using chains: "Only use chains in heavy snow, on compacted snow. Use Land Rover approved snow chains only on rear wheels and only on OEM tire size. Use Grass/Gravel/Snow mode and turn off DSC. Limit speed to 30 mph."

 

Land Rover lists 275/55/20 as an OEM size in snow tires. Chains should be compatible.

From their user guide below



Here is the link

OEM Tire Sizes

There are a few options in that size. Nokians are harder to source it seems.

But their user manual also states.Full-chain traction devices can be fitted to the rear wheels of vehicles with the following tyre sizes:

255/70R18.

255/65R19.

255/60R20.

So I guess they are hedging their bets. Maybe a tire sock would fit with the 275's. It's really only relevant to meet the legal requirement to carry chains. (One I'd guess 99.9% of AWD folks don't follow)

Here in PNW the chain requirements make no sense. AWD vehicles are exempt unless the snow is so heavy that all vehicles require chains. (Never seen this. Usually road condition goes from "Chains required on all except AWD" to "Pass closed" )

I'm not going to get chains for the Defender. They will never be used. I'm in the mountains a lot in winter.

A 2WD with a dedicated winter set of boots is supposed to chain up when a AWD SUV/truck on summer tires can skid about legally. BC laws make more sense than WA's. They simply require triple peak rated tires on all if you're on certain roads. No 2WD/AWD distinction

 

Thanks for mentioning that your wife received a free 2hr LRE upon new purchase. I'm going to keep it in mind to ask about this when I go to pick mine up (hopefully) in December.

 

Tire socks are not full chain but meet the legal requirements. https://shopautosock.mcgeecompany.co...from=275-55r20

Here is a size that fits. Will also take up less space in their never to be opened packaging they come in.

 

Maybe LT's are available in 18" , I do need the T speedindex ( for example I did last week in Germany topspeed in my 90 P300, 112 Mph, limiter engages exactly)
