Hello all
What are the advantages/ disadvantages of low vs high profile tyres?
I’ve always assumed it’s better to have 315/80R22.5 over 315/70R22.5
What’s the difference except for size? Does anyone have identical vehicles but run different sizes on each other? What do you find?
TIA
I’ve moved from 295/80 to 315/70 tyres on the euro6 tractor units. They have a higher load, are a similar weight, and last longer. A315/80 has a higher load rating, but is heavier. It also has a higher rolling resistance compared to a 70 profile.

2.48mm higher and they spin 40 times less per mile but you knew that already [emoji14]

Only talking about this the other day, most of Walkers fleet is now 315/70 can’t comment on exact mileage as tyre damage can finish off an expensive tyre before it’s technically bolloxed.
Changed a set of low rolling resistance drives on a unit the other day because of lack of traction, the tyres weren’t quite ready for re cutting but due to the tread pattern they were useless this time of year
I’m sure I’ve seen an article in commercial Motor that a local haulage firm BJ Waters have been ordering new trucks with 295/80’s due to getting better mileage out of them, I suppose it’s down to your operation and how you load really.
Moving forklift trucks it’s not always possible to get the weight in the ideal place in the trailer due to height/size etc so it’s possible we see an increase in wheel spin especially when you see some of the places the drivers have to deliver to

I moved to 315/70 initially as I was told a 295/80 wouldn’t have capacity with additional front end weight for euro6 tractor units. And Michelin and continental also said go for 315/70 as a 295/80 is pretty much a uk only product whereas most of Europe uses 315/70 or 315/80, so therefore all the latest features appear in a 315 size first, with 295 lagging behind by a year or two.
But then they started producing an XL version of the 295/80 with a higher load rating.
But I’m quite happy with a 315/70, then again I only use Michelin and continental so I benefit from all the latest technology in the tyres to keep the rolling resistance as low as possible as well as the wear rates.
