Stick to Nitto NT01 or try BFG R1 (Or Toyo RR)

which coilover you have?

1.5s per lap is a lot but if they last longer -> that is the balance.

Anybody with experience on Goodyear Eagle F1 Supercar 3R?

Gotcha! If the passenger inside is corded in conjunction with driver being fully worn, then sounds like they're evenly matched for replacement interval? So it's just a function of why? Maybe that was the question all along and I jumped to the wrong conclusion

Could you be getting toe deflection? Do you find yourself scrubbing speed or dragging on right handers? Have you tried dialing back on passenger camber?

Yes, agreed 1.5s is a big difference especially if you're running TT but these aren't tires for a hot lap. If just practice / open lapping, which is 90% of my time on track (~2500 track miles to date this season), I like testing myself and setup on these "slower" tires.

I have the same wheel size on front 18x10 ET25 with 10mm spacer to clear Ohlins R/T. Dont have room to go wider unfortunately.

I am reducing camber on passenger side.

Not looking for TT but something that matches (performance/durability) BFG R1

I don't know if that tire exists. RC-1 in 275/35/18 runs wide (about the same width as BFG r1 285/30). Could run those square.

So NASA has lowered the penalty for using Toyo RR in Time Trials which supports my experience with them. Stick to NT01 if you're considering between RR or NT01. They're not worth it.
