ALL terrain tyres on a 2 wheel drive - ALL 4 or just 2...?

[harky]

Im gonna put All Terrain (Falken AT) tyres on my FRONT wheel drive peugeot boxer - 'cos im gonna go down some silly wet tracks n fields...
Is there ANY point in putting them on the back too?

Can I run AT on the front and stock on the back so long as they are the same diameter?
If the back wheels arent pulling whats the point in having same traction?

Interesting question which I don't have an answer....however you will have issues regarding a spare... assuming you have one and also (in my case) more importantly it will look rather silly.

A simple answer to this is no. If you feel the need for AT tyres they must be fitted on the front and back. I don’t think the tyre centres will let you fit different tyres front and rear for safety reasons.

 

[Lenny HB]

Also tyres with the highest grip should be on the rear for safety that's why newest tyres should always be fitted to the rear.

 

[poppycamper]

Lenny HB... I agree with you but if he has AT tyres on front and ordinary road tyres on rear then you may find (when on road) he does have more grip at the rear. A situation I don't think I would like to be In... case of all or nothing!!!

Not mixed on any axle, traction axle is the front.
Under new regs Asymmetric tyres can be fitted on the wrong side.
This might help, advisable and legal are quite different things.

Not tried AT on front only
Did once try winters on the front and standard on the back on a car for a couple of weeks until the second pair arrived
It was an experience I would not wish to repeat
Plenty stuff on you tube

Just stick em on..... As long as the correct load and speed rating is on all tyres you can fit what you want.

Hardly the safest bit of advice to be giving out pappajohn ?

Not always about going forward it’s about sideways slip as well penny wise pound foolish springs to mind. Having said that you did seek advice before committing yourself.

The problem you will find fitting AT 4x4 style tyres on a motorhome is they will not be rated for the weight, and the tyre profile sizes may foul the wheel arches

 

[tacr2man]

It is better to fit 4 tyres of same tread , load and speed rating , as variance can cause handling problems . I have had personal experience of this with a land rover which was used to tow a recovery trailer . I fitted BFG MT to replace the OE Michelin high load rib pattern ( Defender 130HCPU) having fitted a pair on front had to take vehicle out to do a recovery . It was almost undriveable at over 30mph . When i got back , after a short trip I completed the fitment of the rear two BFG M/T and vehicle was found to be back to original stability .

To be fair though, on his little mobility scooter it won't make much difference!

 

[Minxy]

I wouldn't fit different types front and rear ... apart from what's already been mentioned your insurance company might have something to say about it if you have an accident and thus avoid paying out.

 

[Reusables]

Fit all 4 At tyres on because if you only have the fronts on you'll be constantly worring weather the rear is going to slide out or even the front going round a long wet bend ...all or nothing IMO

As I said, if the load and speed rating is at or higher than specified there's nothing to stop you.
As already said by TheBig1, the load index wouldn't be suitable and as 4x4 tyres stand taller than road tyres they may not fit in the wheel arch.
But there's nothing to stop you fitting them.

Need to make sure rolling diameter is similar to rears. I once had new tyres on the front of an Alfa and they were a bit chunkier than the rears and the ABS system went baserk due to slight change in rolling speeds front/rear

Whilst I agree to change all 4, standard road tyres on the rear will likely have more grip. And if the front AT's are going to loose grip it will be at the same point no matter what is on the back.

 

[fat haggis]

Winter/ Allroad Rubber should be on all 4 corners of the vehicle if not your asking for problems it will make the van more unstable if on on one axel. It’s all or nothing I’m afraid

 

[busbuddy]

116 load rating (1250 a corner) is doable with ATs but profile will be your problem on the front

May also be a problem on the rear too.
Inner wheel arch dimensions arent designed for a considerably taller tyre and may foul on bumpy/potholed roads.

As I said #5

I'm looking for 225/70/16 with 116 LR and am struggling. Closest I can find is 235/70 which comes out wider obviously but 1.4 cm bigger diameter. That's BFG tyres unless you know of any others??

 

[busbuddy]

1.4cm more diameter is only 0.7cm less room from top of tyre to arch

 

[Skez]

Agreed! It's front and rear edges that require clearance for me but will be fine on my PVC!

Inside of tyre on full lock would also need measuring

Odd size the norm is 225/75/16.

 

[Lofty1]

I fitted big at all round only problem was had to fit rubber arch extension on the front to stop mud spraying. Found the steering more sensitive, and a little noisy compared to normal camper tyres

 

[pappajohn]

Overall tyre height of a 225/70 tyre will be a fraction under 29 inches.
Compare that to a standard tyre height.

You're quite correct - that's what I currently have!! Along with fat fingers!
