[DeadChild]

Hi bros, would like to ask that if i change my Spec one tail light cover to clear and use LED Bulb would it be bright? And would i know if i could pass my inspections?

[BioMoDiFIed]

Shud be same for most Spec watever S4...front 36 rear 39(solo) 42(with pillion).

Any way TS, if ur tyre has been used for a very long time, its time to get a change..tyres are permeable. There are microscopic holes in all tyres when you first bought them. This is the reason y you need to routinely check and pump ur tyres. As the the tyres get older thru use, these holes get bigger and thus loosing much more air, faster.

Think of it like a pumped up balloon. After a sometime it gets smaller than the size after u blow it up. but there is no puncture sign on the balloon. This is also due to the permeable characteristics of the rubber...same goes to ur tyres..hope this helps..

actually, there isnt any specific tyre pressure to pump.

jus make sure u pump a pressure that can suit to your riding and handling.

 

more air = less wear & tear = better FC = less grip = more slippery

less air = more wear & tear = high FC = more grip = less slippery

 

so, more or less air? u choose...
