I have a set of Mickey Thompson SR 31X18.00R18LT. Im running 20 psi in them but seems that at the hit of the throttle they spin. How low can I go for driving on the street and still be safe?

Anyone running these tires?

are they drag radials or a tube type slick? you may need to lower that tire pressure and do a bigger burnout and how long have you owned them they may be hard and no good anymore :yes:

No tubes there radials. There brand new

I run mine at 18 psi and they break loose real easy compared to the Sportsman Pro's I used to run. Mine are 31x18/15. I ran them as low as 14psi before.

I had the sportsmen pros before also.

So no problems running that low of air pressure. Mine are on 20" wheels
