Yes but it therefore follows that you shouldn't exceed the speed rating of any tyre you apply. The load rating however requires further calculation.

Didn't LR put MTRs on their G4 vehicles?“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

More to the point caverD3, don't they sell the G4 vehicles with MTR's, thereby making the MTR's an OEM fit option I believe that every human has a finite number of heart-beats. I don't intend to waste any of mine running around doing exercises.

UK speed limit 70 MPH Q rated 99 MPH where's the issue
While the UK speed limit may be 70, having a tyre with a lower rating than that specified by the manufacturer will give plod an excuse to keep you at the roadside much longer if you are pulled on for a failed tail lamp.
Depending what Plod consumed for breakfast he could decide there has been an unauthorised modification to the vehicle, thus your insurance is void, and then do you for driving without insurance, or is not compliant with the vehicle's type approval, so is not roadworthy and do you for that, or just give you a friendly roadside chat an tell you to fit correctly rated tyres as soon as you pass the next tyre shop..... Ian's little sticker by the speedo may act as a mitigation and convince him that Ian knows what's what, but you can't be sure.Rob Smith

Ignoring G4 vehicles for a minute - Given that the standard Pirellis or Goodyears are all (18 & 19") V rated, using that logic would mean you could not fit winter tyres which are all H rated, an AT2 on 18" is also H rated.
Where's Andy from AJS when you need some professional input to a thread
edit: on second check of wiki, noted that 17" only available in maximum of H rated!I believe that every human has a finite number of heart-beats. I don't intend to waste any of mine running around doing exercises.

Having seen the other thread and noted you are running AT2's, have you considered the risk of having your insurance voided for running lower rated tyres to be acceptable then I believe that every human has a finite number of heart-beats. I don't intend to waste any of mine running around doing exercises.

I thank you
As with any changes to your vehicle, just make sure your insurer has been informed 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Well i'm even more confused now. The garage, who have been thoroughly decent and approachable about this, have been to the MOT station and been categorically told that the car is roadworthy and would pass an MOT with the 108 rated tyres. I guess the manufacturers recommendation is just that and not legally enforceable. I will look into it further on Monday to make sure.
The garage have offered to supply Wranglers at cost price as a favour- £130 each so may take them up on that. Was quoted £175 at my local tyre place.
I do 25k miles a year so have got used to spending lots of cash on tyres, my last car used to manage about 8k on a set. I also got the car at a fair price so don't feel inclined to push it too far. Tyres are not a huge cost compared to my fuel bill.

At 1000kg's per corner 108 would certainly satisfy the law as would a lower speed rating. If you had an accident though and it was found that you were exceeding the tyres capability you would be liable to prosecution. I.E. if you had lower weight rating but was subsequently overloaded ....or if you had a lower speed rating and was subsequently exceeding that.
Where the manufacturer recommends however the insurer will apply the OEM recommendation UNLESS you have agreed the change with the insurer. Lower speed rated MT\Rs are accepted by my insurer ( I had it put on my notes) and they are perfectly legal as far as the law is concerned 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021
