Tyre pressures when warm

[Mrjoolz]

Read in manual that tyres on my ZZR600 should be 36(f) 41(r)

However, after a 15 minute ride, I popped into garage to fill up bike and did tyres also.

Paddy told me that inflating tyres when warm means over pressurised. Is this dangerous? I let some air out when paddy told me and will check again tomorrow morning at garage round corner

Could the tyre explode if I use bike as is and tyres get warm?

Thanks in advance

But always check the pressure when they are cold.

as tyres get warm, so do the air inside causing it to expand and increase pressure, so if anything checking the tyre pressure when warm will give a a low tyre pressure when at correct checking temperature

Setting the tyre pressures when warm will leave them a bit too low pressure as most pressures are stated for when cold.

As an idea, when riding on track generally you go for 35/35 with hot tyres - obviously the tyres tend to get a fair bit hotter on track due to the constant (ab)use.
Cold pressures tend to be 29-30 for the rear tyre when cold and 31 for the front tyre when cold to get the desired temperature of 35 when hot.
So it's not a massive difference.

First race I got a 4th place in (got a few more, but never managed a podium) my tyres were at 55-60 psi. So, your're not going to die if it's about out either way .

My manual states that the rear tyre on my ZZR6 should be 41psi.

Does that seem a little too high, as Paddy told me his Gixer is 36 (for both)

My front is 36 again according to manual

When I pump my tyres up (have compressor and foot pump in garage) I put them to the manuals pressure. When I've ridden out and about for a while I went to check them again (slow puncture on front) the rear was about 4psi over... im guessing due to the warm tyres.

Front was down about 5

You are literally a stones throw from my house Next time you are passing through stop in for a coffee/tea/cold drink, let your tyres get back to normal and feel free to use the pump... its pretty hefty

41 for a rear is quite common I believe.

My bike is 28 and 26
