Really exciting tyre pressure question

[8IKERDAVE]

Last year I treated my Speed Triple to a pair of Bridgestone S22's. Great tyres, lots of grip in wet and dry, however the rear is completely shagged after around 2500 miles. It's not been on track, don't really use motorways if I can avoid them and I run the pressures a 38R / 35F. I've played around with pressures and found this to be the sweet spot but 2500 miles seems a bit excessive. Should I look to raise the pressure a bit to squeeze some more life out of the replacement it's going in for next week or stop being a moaning bh and budget for a rear tyre a year?

I cant believe your tyre pressure is that far out to make such a difference in mileage.

I would try a different tyre. I can get 3500-4000 miles out of a Pirelli Diablo Corsa II on my MV Brutale 1090. It came originally on Supercorsas which lasted under 2k miles on the rear. I do 3-4k miles a year on it, and 2 sets of tyres a year was a bit excessive for little benefit. The Diablo Corsas are much better in the rain and dont seem to have any negatives in the dry.

I have an S22 on the front though which has plenty of life and don't like to mix / match them. I normally change my front every 2 rears so will look at an alternative then.

Difficult to comment on tyre pressures as suspension settings can have a huge effect. What does the tyre look like? Melted snot or orange peel?

I run 36F/42R on my 1050 engined Daytona and I don't think I've ever managed more than about 3,000 miles from a rear even with the 955 engine.

Don’t think pressure would make that much difference. Maybe buy another new rear same same since the front is still ok-and up the pressure 1 psi.

Any reason for running 42 other than the handbook says so?

I run 36f 36r on my 17 1050R and I get around 3k out of my Supercorsa's. I do ride on tight twisty roads more often then not though if I can help it.

My ohlins suspension is set up for sport/track as I like the bike to feel nimble at the expense of a little comfort during the summer months. I dial it back during the colder months though. Might be worth looking into the set up on yours ?

I've not long put a metzeler 7rr ? On the front with the intention of replacing the Supercorsa rear with the same tyre. The SC's are not great in colder conditions and I hate it when I'm on roads such as the A5 where its almost like the motorway, as they can square off very easily imo.

If the the bike is being used on the road only then I'd ask what tyres that last 3000 to 3500 miles give that the likes of the Road 5 or the RoadTec 01, which will last over 7000 miles, don't give? I have never found such tyres wanting in any road situation, on bikes with both more power and more weight. There's enough dry grip to drag hero blobs and more wet grip than anyone with the slightest self preservation instinct can use. If you're riding beyond the capabilities of a Road 5 or a RoadTec 01 then I'd be suggesting you shouldn't be riding on the road.

Totally depends on the rider/bike really I would think. Using the torque from pull away; getting up to speed rapidly; mashing the tyre into the floor with 250kg+ loading while the front is barely touching the floor - another job I wouldn't want; being a rear tyre on a sportsbike.....

I suspect your usage and riding style will have more impact than small differences in pressures. If you want to get more miles then changing where/how you ride may help or change to a harder compound tyre?

Personally I don't think I've ever had more than 2k miles out of a rear but that's because I only ride for fun and generally buy soft compound tyres.

If you want something with a bit of longevity but without going for full on touring/road tyres then stuff like the Metz M7RR or Michelin Pilot Power 2CT may suit you.

Because it works.

The tyres wear with an even 'orange peel' effect without any stepping on the tread pattern and If I run the pressures slightly lower it doesn't want to turn.
