I absolutely hated the stock gpr-300s on my ninja. In the dry they worked fine (only lowsided twice in a parking lot from trying to make the smallest possible circles), but I slid out constantly in the wet (thankfully never crashed) at normal lean angles and not very much throttle. I replaced them after about 4k miles.
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.
I got myself the Grantrek AT5s. For me they have a good compromise between traction offroad and road noise on tarmac. I also fitted a full spare with one of those AT5s on it. Fits perfectly where the 3/4 sits.
Mine held up really well and was decent on the road and hard dirt and gravel.
Loose stuff though? Not a fan.
Just about worn through my D605 on the front.
Wonderful on road. Not too loud and gives you plenty of grip in the twisties. Have found some cupping after it’s worn down but that’s pretty normal for any knob tire.
Off road handles hard pack dirt and gravel easily. Rocks and roots are okay as well. The only area is had little traction was soft sand and mud. I haven’t found a good front tire for mud yet so that’s expected.
Overall for the price and rating as a 50/50 tire, it handles very well.
Mine have 30k miles on em and I live in Cali and they havent given me any trouble. I drove to Utah last year as well for a camping trip, they held up good in the heavy rain and dirt. I plan on swapping to an all around better tire though next year
I had my WRX for a year and a half, and the entirety of it spent on the stock Dunlop tires.
Above 50°F, go ham. Have fun. They're great.
Below 50°F, don't take high speed corners. If you normally go 40 around a corner, go 35 instead.
That being said, I never lost traction with them, even in 40°F rain. The only time they ever broke loose was when there was snow on the ground, which is expected.
They're good on 40+ weather. And they're loud. Freaking louder than the Blizzaks and those are snow tires with huge knobs. They're stock tires so use em as much as you can then buy better tires.
