1999 Tahoe LT. 5.7 SFI. 4x4. 2door with a three inch body lift. 105,000miles.
I am running 305 x 16 Goodyear Wrangler AT/S tyres. If I inflate the larger tyres to the manufactures recommended 35psi, at 70mph the rear starts to weave from side to side, but when I increase the pressure to 40 psi all seams OK.
I imagine that it is the tyre walls flexing that causes this.
Do larger tyres require an increase in preasure and is it OK for me to run at 40psi?
Thank you, RoyC.
have the same problem?
