What tyre pressures do you guys run AT3s at?, I've just got a set in my RRS and they're at 30 psi, seems a bit low.


33-36 it's a all terrain tire with maximum pressure at 50 psi

Do you find the ride is harder due to the 45 profile?


I haven't noticed anything different in ride or behavour on the road. No extra road noise either which suprised me.

No rubbing issues.

Haven't really tested them in the mud yet, it has been so dry here for the last couple of months there hasn't been the opportunity. I'm sure that will change soon...

Are these tyres suitable for mainly road use or are they a bit overkill?

Given the AT3 has the Snowflake symbol is it classed as a winter tyre/all season tyre or do I need to buy dedicated winter tyres?

Even though my Mrs drives the truck 90% of the time as a school bus, my logic was that I went for the V spec which is C wet rated over the H rated E class giving pretty much the same performance as the Pirelli Zeros. Wasn't fussed about the fuel rating as we only do c6k mileas a year.

Also probably worth mentioning the cost saving vs Pirellis, the wear rate and the improved side wall protection.

Otherwise, biggest other thing for me was noise. Id heard that they were quiet by other members so went for it. Got to say I cannot notice any difference between the old Zeros and the AT3s.

Yet to really test them on wet roads yet but thus far they really haven't put a foot wrong.

Just got them fitted today. Bit disappointed in that they don’t look as agressive as the AT2s, but noticeably considerably quieter than my AT2s. Car feels very different in a good way. Had loads of sets of ATs and this is a much better tyre IMHO on road. Not sure how it will work off road. In two minds, kind of prefer the look of the AT2s, but prefer the feel of the AT3s.

I had hoped that the new AT3 had stronger sidewalls.............

It would not appear to be the case, 2 weeks old and a wrecked tyre





Now replaced, but that has thrown up another issue, a new 255/55R19 AT3 does not fit into the spare wheel well with the Tow Trust Towbar on ??

The side arms effectively circle the rear of the spare tyre and reduces size....


Any ideas, apart from taking the towbar off, which I am a bit loathed to do as I do tow occasionally - can the exhaust shields be bent a bit ??Will that make any difference ??

TIA

Put it in partially inflated and carry a compressor?

I was never convinced by the new Grabber after destroying some of the older A/Ts with the chocolate sidewalls!!

I am considering buying a set of AT3's for my 20" wheels, However I'm a bit concerned about their performance in muddy / boggy grass conditions. (Most of my off roading takes place in the winter on muddy tracks and wet fields) They seem to be very much orientated towards wet roads and snowy conditions, even the construction / tread pattern looks like a snow tyre, and as anyone who has driven in muddy conditions on snow tyres knows; they don't perform at all well, they just get clogged up straight away!

I was quite happy with my AT2's on my old disco with 19" rims in fact I still have a set of part worn AT2's on 19" rims which I plan to run this winter.... but then what?

Would appreciate any muddy feedback Thumbs Up



Put the AT3s to the test yesterday at a farm clay shoot, going up a steep up hill mud track, across sodden grassy fields and sloppy mud ruts. While some 4x4s were skidding and sliding all over the place my disco remained straight and true. Ha ha wish I had recorded a big Porsche 4x4 thing (Cayenne?) trying to do a Clarkson digging itself a deep hole.

Only had it in mud and snow mode (rather than using the paddles) but has given me a great deal of confidence (not to mention a sore ear when the Mrs saw the state of the school bus) to explore.

You need to get the rear edge of the tyre up behind the tow bar fitting first and then winch the front edge up. It will fit but it's tight and might need a couple of attempts to get the technique. It will fit but it's jolly tight assuming the AT3 has the same dimensions as the 255/55/19 Grabber AT. If not, I'm going to keep the AT spare I have currently for some time!

My AT3s did ok at Les Comes this year, Chris. No signs of any sidewall marks, unlike the ATs last year.

Just fitted 4 x new GT AT3s, I think the road noise is noticeably quieter and they feel very sure footed on the road especially with the recent flooded roads. The sidewalls don't seem to bulge out like my old AT2s did (they always looked a bit flat). Not had chance to try off road yet or towing.

I drove back from Cheltenham to London last weekend in the snow and the conditions were terrible. M25 north was a skating ring with multiple crashes and cars out of control. No problem at all with the AT3's on and felt very sure footed.
