Grabber AT3 fitted today

This morning finally got around to fitting a set of General Grabber AT3's. In the end I fitted the same size as previous rather than going up one profile. Therefore the tyres are 275/40 R20 106V. My insurers agreed I could go to '45's without charge but I didn't want the extra hassle come renewal time - having to explain to each quoting insurer what the modification was to the tyres.

The cost for the four was £596.76 from Tyreleader and fitted in Northampton for £36 (incl VAT). Therefore a grand total of £632.76 which is not bad for 40 profile and V rated.

So far I've only driven about 8 miles on them and therefore no significant comments apart from no increase in road noise (speedo was reading 110 - hope that was KPH lol).

Any suggestions on tyre pressures - standard or has anyone found AT3s in this size better at higher/ lower pressures?

If you want road tyre-matching wet tarmac performance, don't buy an AT tyre. All ATs score around E on the EU wet score. They are a compromise tyre so something gives. The AT3 is winter rated, however, and does pretty well in snow. Something that the pure road tyre won't do unless you run summer and winter options.

If you need an All Terrain tyre then you put up with the reduced ability on road. Having said that, I found the AT3 to be very good on road - certainly good enough that the driver backs off before the tyre gives in. Thumbs Up

The Blizzak is a winter road tyre. Ain't going to get you places that the AT3 will get you off road. 2012 SDV6 - it's missing a couple of cylinders

I've kept the old tyres as they still have 5-6mm left on them - and probably re-fit them as and when I re-sell the RRS.

To be honest, although I use the straight line performance of the car and do hustle it on the twisty roads - as RRSTDV8 says - I'll probably give up before a road-biased or AT tyre got to it's limits. The main thing is that I need more off road ability for leisure (shooting) and for work that takes me around farms/ country estates. The old tyres just about made it through the first year of ownership but I was left a number of times where I walked/ took a lift when instead I could have driven my RRS with a decent AT tyre. There is no replacement for displacement - W O Bentley

definitely the tyre for you so Thumbs Up

i was considering a pair of Cooper WeatherMasters to replace my nearly worn Michelen Alpins.
ive driven SUVs in the mid west US with these and they seemed great.
But the test reports on alltyretests.com are not great.... Shocked
Vredesteins Wintrac have served me well in the past and are good in a field too Laughing

will have to research a bit more.
since the missus drives it as her daily driver during the week... i am reluctant to switch up to a specialist off road focus tyre 2007 TDV6 RRS HSE..now gone

Have these on a D4, and had the older models on a D2.

Always found them to be perfectly OK for all weathers and the road miles that I travel.

Depends on how you drive and what you expect from them..they are a compromise at the end of the day.

I can never understand the thought of having a motor that will cope with most things, but then having road oriented tyres.

The few days that we have where the car is that little bit more useful that everything else out there, makes the AT worth having and making allowances for. 2011 MY D4 HSE

Indeed so. I'm looking after some sheep for a mate for the week. It just means driving around the fields to make sure they're ok, etc. At the moment the ground is very wet. I've had a couple of moments on my Pirelli AT+, notably on Monday after the heavy rain of Sunday. I had to back off and have a bit of a run to get through one gateway which was very slippy and slopes up after a bump on the exit. Even with ATs, it was touch and go. On road tyres? It wouldn't have made it, I fear. Other areas where the ground is sloping, picking the line is critical - there are areas that are very wet and getting stuck is a real possibility. Heck, my mate got his Defender stuck the other week and had to use his tractor to pull it out, it's been that wet. I really hope I don't get stuck - not sure who to call if I do as he's away!

Nobody call me if they get stuck in Northants.. I've only got a Halfords stretchy tow rope and no idea where the towing eye is Whistle Laughing 2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

Almost needed a tow this morning. Ground very wet and driving through a gateway in tracks, on to old ridge and furrow pastureland, it just ran out of momentum and sat there with the diff locked and all four wheels slowly spinning. Took a minute of backing up a bit and running forward to get out. I've extended the track from the gateway by about 50m now. Two long parallel lines dug in to the grass. Whistle

I was eyeing up the sheep and wondering how many would be needed to pull 2.5 tonnes of RRS! Rolling with laughter

As usual, it's wet grass over soft ground that tends to get you stuck. These things clamber up rocky tracks like mountain goats but a wet field can stop a 4x4 quicker than dropping an anchor. Once there's no traction, you're Censored , even with traction control trying its hardest. 2012 SDV6 - it's missing a couple of cylinders

Would it have been worth dropping the tyre pressures to say 15-20 PSI - doubling the tyre foot prints and then re-inflating as soon as you reached a hard surface? There is no replacement for displacement - W O Bentley

I did wonder but to be honest with relatively short sidewall tyres on these vehicles, you don't get the same effect as you do with the big high sidewall tyres. You certainly don't get much of a footprint increase and you do risk pinching the sidewall on a low sidewall tyre if you suddenly hit a firm bit of ground or a big stone. 2012 SDV6 - it's missing a couple of cylinders

Interesting aside - I was just looking at a colleague's all terrains in the office car park. They are 265/75 R16s and even with their greater side walls they still look slightly low in pressure/ large road foot print. A little more reassuring that mine aren't too bad either now there are at 40 PSI (assuming the 265/75's are running enough tyre pressure).

Below are mine at 40 PSI and colleague's AT''s on his Defender.
