Been running a street radial 100-120 treadwear for 4 months done 3600km, on 20psi cold, finally some grip for once. I do a lot of highway kms but only a weekend car, basically blowing the tyres off instantly now in 5th even 650hp manual Ute. All grip is gone heaps of tread is left though. Apprantly they have limited heat cycles and could have gone off or needs a proper burnout to get to some fresh rubber. Have ordered nitto nt05 as they were on sale and are more street friendly 200 tread wear so maybe get more out of them I’m hoping. Just unsure on pressures should I try a higher pressure for highway then drop when we are having a run? Let us know Link to comment Share on other sites More sharing options...

Are there any bushings that have deteriorated that could let the diff move around a bit? That would make you lose grip easier, as would worn suspension. I run a bit over 40psi for highway driving with low profile tyres. Link to comment Share on other sites More sharing options...

I’m more after semi slick or radial tyre pressures from different brands and highway/track psi. I had the pro street radials at 28psi for highway but were bit bouncy went down to 20psi and were so good in FG manual Ute held 2nd 90% of the time with enough speed. Thinking these nitto nt05 s are more a street tyre now so I could try 32 and see if any grip is there if not I’ll drop to 24 and then 20 🤙 Link to comment Share on other sites More sharing options...
