First of all I'm new here, currently living in NZ, not Kiwi, but from Philippines. I've been a long time fan of WRC which started in computer games, watching seasons and now practicing in real life to get some skills and maybe join beginner comps.

Currently I'm using the 96 Toyota Starlet (ep91) NA. All Stock except for some engine mods (a true cold intake with ram and resonator) and 13" rims. Unbelievably durable car in offroading for a fwd so I'm thinking of getting another Toyota for more serious rallying like the classic Celica GT-four.

It's on M+S (all season mud and snow) passenger tyres at the moment (165/70/13 Westlake SP06 38/30 psi f/r). 5000 kms daily driving, few hundred kms of gravel rally practice with 60 kph average speed but is drifted a lot on corners and hit the banks hard a few times(can't believe it did not de-bead!). Still looks okay, plenty of thread left, no distortion, no bulges, and only minor scratches on the thread, almost none on the sidewalls! Most I practice at the moment is flicking, throttle oversteer/power understeer on relatively sharp corners so you don't need to be fast, minimal handbrake turns-as they seem to wear/damage the rear tyres the most.

I'm wondering if there are better tyres for slow practice runs, preferrably more durable and possibly more grippy except for true rally tyres (can't afford them and they don't last!). I've come upon Light Truck tyres on my research but are they legal to be fitted on a passenger car by NZ laws? Are there ones on 165/R13 or 145R13's still?? Are they significantly heavier that it badly affects unsprung mass to total mass ratio? Could I also fit dissimilar sizes, 165R13 front and 145R13 on rear to get more grip to the rear in gravel but I also wonder if it will cause issues in daily drive/laws? Thanks!
