On the road run the pressures in your handbook. If these differ from the tyre makers recommendation, go with the tyre manufacturer. If you’re riding in really hot weather drop the cold pressures by a small amount (1-2psi) but check the pressure when the tyres are hot and ensure they’re not higher than the recommended pressures.
On the track, with road-going Sports tyres, you’re looking for pressures of between 30-34psi hot in the rear and 32-36psi hot in the front. This translates to around 28-31 cold in the rear and 30-33 cold in the front. If you are running tyre warmers, make sure your hot pressures are no higher than your bike owner’s manual’s recommended pressures.
With road legal race tyres, recommended pressures vary a lot, so check with your supplier. The latest Dunlop and Bridgestone race tyres, for example, run at 18-22psi hot in the rear! Don’t ask your mate the bricklayer, ask the manufacturer or tyre dealer.
Hi Two Tyres,
I tour Spain and Portugal in summer on a 2017 Triumph 765RS fitted with Metzeler Roadtec 01SE.
Can you please recommend cold tyre pressures for solo riding with luggage.
Best wishes,
Julian
Hi Julian, we recommend keeping to the pressures in your owner’s manual. That said, tyres can get hot if worked hard in hot conditions, so I’d be looking to keep them to 36psi front and 42psi rear when up to temperature.
