- Speed rating on tyres
Not related to load, no – your tyre size and inflation pressure are related to tyre load, the speed rating is the max speed the tyre can take for 10 mins at its rated max load. If you overload the tyre you effectively reduce that max speed rating I suppose, but they’re meant to be selected size by load, then speed by max speed. If a manufacturer was speccing a higher speed tyre but on oddly sized tyres for the car I’d find it a bit odd! There are very few cars that NEED a Y rated, I’d be interested to see if it’s spec’d in the handbook and which model you have!Posted 9 years ago
My current tyres are rating ‘V’ and i’ve looked this up and that is good for 149mph. The next one down is ‘H’ which is good for 131mph. I dooubt very much that I’m going to do either of those speeds, and i’m certain i wont be doing them for long enough to make the tyre disintegrate.
So my question is this: Do i really have to have the ‘V’ rating that is currently on the car or will the lower ‘H’ rating do ok?
I do a mix of town and motorway driving. most of the motorway driving is not just short sections on the motorway, it tends to be for about 20 junctions or something like that.
I’ve had a quote for the lower ‘H’ rating tyres which is over £20 cheaper than the same tyres with a ‘V’ rating so worth saving.Posted 9 years ago
