Was wondering if anyone else was running BT-021 on a tt600 or s4 and what pressures you have them at?
I have had my rear at 42psi and my front at 40psi as i take pillions quite a lot and was surprised when i looked at the recommended pressures in the manual and what pressures people are running at in the tire threads

Bridgestones typically run at higher pressures than other tyres, Dan...42psi on the rear sounds spot-on....40psi on the front sounds too high...think 36-38 is more correct...prolly 38psi IIRC.

I run 36/42 on my Sprint GT's 021 tires, which is the reccomended tire pressure. My dealer, however, always want to go with slightly lower tire pressures.

It depends a bit on what you are doing and what the conditions are like. For every day street riding, going with the manufacturer's recommendations is a good idea. For high performance, carrying loads, or extreme conditions of one kind or another (heat, cold), you may want to adjust pressures. To get a little hotter tire surface, lower pressure. To run a little cooler or carry heavier loads, raise pressures. You will want to check with somebody who knows a whole lot more than me to make sure you have the exact limits of these things, but that's the general idea.

Go soothingly on the grease mud, as there lurks the skid demon.

For BT21's the best pressure is 0. I know it's a smarta$$ answer, but that's all I got....

Thanks guys, i will drop the front down to 38 and just leave the back at 42 as i can't be bothered to change my pressures everytime i gie someone a pillion!

Whenever you move from the OEM tire to another brand you must use your new tires' pressure as recommended by the manufacturer. Bridgestone has a number you can call and actually speak to tech. They will give you the proper PSI. 42 sounds a bit high to me.
