Tires DUNLOP or FEDERAL

205 65 15 Federal Federallys

They have great traction in the dirt and never de-bead

Last two tires I ran were GPR300s. The traction was good in the corners, only negative for me was the lifetime, only 3,000mi each before having to replace.

Dunlop is a fine brand and the Sportmax is perfectly good tire. You will be fine.

So I came to event day on my normal Dunlop SP Sport Maxx tyres. In practice, I found that on the R-spec I could do an 89 second lap, but consistently run at 92 seconds (I could do consecutive 90 second laps, but brakes would become the weak link after about 4 consecutive laps). On the street tyres I could do a 93 second lap, but due to brakes again, nominated at 95 second lap.

do these tires fit on stock 370z wheels ?

Chinese tires now are pretty decent and are a bargain. The only serious issues I've faced surprisingly were from branded ones - I've had bubbles on Yokohama and Dunlop.

Federal 595RS-PRO 275 width - Lower grip levels than RE71 or similar, but they wear like rocks. I am on heat cycle 15 and they have no significant wear. Time deltas for me on a short, technical track are ~1.5-2 secs slower than my other tires, however.

Swap them out! The Dunlops are unsafe below 40F.

Not a fan of them. They grease up so easy. About burned through a rear in a day running on dunlops recommended hot pressure.

at 18000 miles I had to replace the Dunlap tires on my 2021 rogue sl. flat tires and in the danger zone of 2/32. I have never had to buy tires on a new vehicle at 18000 miles.
