Larger tyre question.

[voltron]

A weird question but I figure I will ask anyway.

Does fitting larger tyres mean the truck can carry the load more safely because it's a larger tyre hanadling the same weight that a smaller tyre did previously???

Im not asking if it increases your load carrying ability, just does it minimise risk of tyre damage or blowout because they are larger.

No, tyre load rating/construction matters not tyre size.

Why do you think a bigger tyre would be less likely to blow out? Ramp angle?

no it doesnt, the load rating governs the max load of the tyre and in most cases upping the tyres load rating is of no advantage because the axle limit comes in to play first.

increasing the tyre size can, in some cases and situations, increase the chances of tyre wear and damage.

I've noticed for many tyres 285/75-16 is about their highest load rating. Bigger tyres like 315/75-16 have a lower rating, as does 265/75-16 and 305/70-16.

I only ask because with so much weight on board when on a trip, I often think about how to minimise the chances of damaging or blowing out a tyre. I try to stay on top of correct tyre pressures and driving to suit the conditions.

Tyre blowout for whatever reason the one real concern I have when carrying close to GVM.

[Blknight.aus]

fit truck tyres, but it wont really help as most blowouts are caused by tyre abuse and running too low pressure for too long at too high speed.

tyre stakings generally tend to result in a rapid but controlled deflation that unless you are operating near the limits of your available grip are typically within the scope of a normal persons managability.

While I've had plenty of flats, I've only ever had one "blow out" and that was because the lock ring failed on a 3 piece split rim, I was in a fully loaded mog, near high way speed and it was the front left, Worst part of the whole experience was the noise of the tyre letting go the loss of control was neglible BUT I was running on the straight at the time and wasnt in any kind of tyre demanding driving situation.

One of the remote tyre pressure and temperature monitor devices should ensure a bit of peace of mind and possibly save a tyre or two.

You are somewhat correct as larger tyres often have a higher load rating.

However this is more associated with Light Truck ratings.

For example the 265 65 18 BFG AT is Light Truck rated & has a huge increase in load carrying capacity especially when compared to OEM tyres.

You have to balance the size against what will fit & what is legal.

The equation is made more difficult with 18" 19" & 20" tyres.

I would agree that if the tyre has a much higher load rating then you should be stressing the tyre less providing the vehicle load remains the same.

Ok thanks.

Next question then is, what is best all round performing AT tyre which fits, and is legal and has the highest load rating.

I have BFG's ATs in 245 70 16. They are light truck and only a few mm taller than standard. So legal. They are the closest BFG size to standard in light truck.

I've had maxis 751s before too but in 235 85. They were also light truck but IMHO too big for my disco in the hills. And they weren't legal.
