AT Tyres
 

I am going to buy new tyres for my Iveco 40-10 4x4. I am looking at all terrain with a load rating of 1400kg. has anyone got experience with these
General GRABBER TR 235/85 R16 120/116 Q » Oponeo.co.uk

or any other options or opinions

The ones you have linked to aren't GG ATs. They are TR which is a summer road tyre. Also, are you sure the load rating is ok for your truck?

I had the GG AT2s on my hilux and liked them. useage was almost exclusively road based, but they performed quite well in mud for an AT tyre. I think they are also winter rated. Fuel consumption was slightly worse compared to the original Bridgestone duellers which were more road biased (and crap!)

It is worth noting though that most desert racers use a MT pattern (usually BFG). This seems counterintuitive because they would dig in more but I believe it is due to the greater number of plies in the sidewalls which means they tolerate airing down better and they are more resistant to sidewall damage from rocks etc

I've never used MT tyres in sand though, I used proper sand tyres

you could probably get 9.00x16 ex military tyres for your truck (assuming they would fit) in a sand pattern if you were going in sand or something like a michelin XCL or XZY pattern for more general use. For more road orientated use there is a tyre I can't remeber the name of that was standard on the snatch landrovers which had a very good ply and weight rating. Those are also available as 7.50x16 of course but I think your 235x85 sits between 7.50 and 9.00 in terms of tyre diameter

LW Vass have a good supply of ex mod tyres (including new) at very good prices

Thanks moggy,

What about these General GRABBER AT 235/85 R16 120 S OWL » Oponeo.co.uk

The thing is I am almost always on road at the moment with some use on tracks and the occasional muddy field. With this in mind I don't need an aggressive tread pattern.

I have looked on LW Vass website but they are not listing any tyres I will call them next week.

More thoughts Please

First thing is look at your axle load plate and see what your max weights are. Then you can use following to see if the tyre you ae choosing meets that requirement : Load Index & Speed Symbol - Info - Bob Jane T-Marts

235/85r16 is metric nearest equivalent to 750x16 , but you need to ideally stick with one or other , in emergency fitting an odd one is ok preferably to rear axle.

If you are intending 99% on road then Michelin XZY would be the way to go
and a set of tyre chains for when you are in bad traction conditions . If its more track or offroad then BFG MT are a tough (3 ply sidewall)long wearing tyre that will give good traction off road /mud , but are a bit noisy on road at speed . JMHO&E

Not used that one either, sorry! mine are GGAT2

it depends really what your needs are. On the rare occasion you go off road, how important is traction, is it worth getting a more aggressive tyre for that 1% of the time you might need it or as Tac says, would chains be a better emergency option (although they make a hell of a mess of the surface)

Tyres are a very individual thing, what suits one person won't suit another. What you can say is, going with GG or BFG you won't get a crap tyre. Then it's just a case of what suits you and your needs best

Look at Vrakking Tyre. Michelin 8.25R16 XZL (34.0") or 255/100R16 XZL (36.5").

Thanks again for the advice.

I am running XZY at the moment but I am finding it hard to find them (if anyone knows a supplier). I looks like the GG and the BFG AT's are a reasonable price and siutable for the load rating I need (120 1400kg single). Both can run with tubes so will be OK with my split rim wheels.

Another point is changing from 7.50x16 to 235/85 r16 seems like a good idea as 7.50x16's seem to be rare at a 120 load rating.

More thoughts welcome

Graeme

Michelin also make a 235/85R16 XZL O/R rated at 120Q. All steel like their other tires, XZY, 8.25R16 etc.

Charlie

Re your comment about running tubes, any tyre can run a tube ( limited by speed rating on some car tyres) , just make sure that you buff out the quality control labels , its not good enough just to peel them off , as its the adhesive that causes the tubes to perish in a very localised manner. HTSH

I'm not too sure about running these with tubes, I think they have ribs on the inside that will abraid the tubes, don't quote me on that, but worth checking

Anyone know what Cooper tyres are like? They do a Discoverer AT3 with a 120 load rating. Good prices too.

Michelin XZL are good for sure but at £150 each a bit expensive. With the amount of miles that I do they will probably perish before they are worn out!

I am not being tight just thrifty, If I have to spend big money then I will....Just rather not!!

235/85 r16 too big for 5.5 rim
 

I have been told by a tyre supplier that 235/85 r16 are too wide for a 5.5 rim. If this is the case Then I cannot find any AT tyres to fit! What are others using on there Iveco 4x4s? XZY are out of production in this size and load index.

What are your opinions?

Graeme

Just to assuage your worries, most truck type tyres have a fairly rough inside appearance , and as long as the tyres are inflated to the right pressures for the speed/terrain then you will be OK . I back this up with 15years experience as a tyre dealer in Australia , which is a severe test of any tyre :thumbup1:

Are you sure that you have the right tyre /rims as the pics of iveco 4x4 ex police etc look to have a somewhat larger tyre rim fitment ?

Thanks Tacr2man,

So what do you think about the BFG 235/85 being too wide for a 5.5 rim? The police Ivecos that you have seen I think have military rims which are 6.5.

Regards Graeme

VAss used to have the full range of Michelin tyres. I bought new 7.50x16XZY off them 9 years ago for £50 each!

5.5 inch rims, thats narrow!! I think thats less than an landie standard for 205s isn't it?
