As we head into the warmer weather and trackday season, I need to get some new front tyres for the GT4. I’ve run the Dunlop Sport Maxx Race 2s since I purchased the car and have only so far changed the rears. I’ll be honest that I didn’t check them when changed at the end of last year at the local OPC but they fitted N1 tyres from 2019 (somebody else was reporting similar on another thread - anyway I will likely finish them off this year due to wear so no biggie even if a bit annoying)!

Looking at fronts, I can only see N2 options available. I understand that this is the newer version of the tyre but my questions are:

• Any real issues with mixing N1 and N2?
• Would I be correct in assuming that now N2 is in production, N1 will be discontinued so ultimately I would need to move to N2 or keep buying older stock tyres?
• Has anybody had their OPC get funny with mixing N rated tyres? To me that sounds ridiculous but you never know! To be clear, both axels will have the same rated and age tyres, just N2 front, N1 rear.

Thanks all for the replies. I can’t see the N1s for the front online anywhere however it sounds like they tend to stop making them when a newer version is released so I guess the options to keep all the same N rating would be either to shop around and find an older set of N1s or change all to N2. It does seem like a real waste to bin a set of N1s that still have 5mm tread so I’ll just keep them for now and have N2 front / N1 rear and will change the rears to N2 in a few months when needed

The Dunlop N2’s appeared as a result of GT4 RS homologation. How or what changes Dunlop made hasn’t been disclosed. The official EU dry grip, wet grip and noise ratings are the same. I’d guess a stiffer sidewall and possibly compound changes around the shoulder to accommodate the geo changes with the RS.
But these would now be the n rated sport Maxx race 2 that Dunlop produce right? I.e. they won’t continue to manufacture N1 and N2?

Yes both are well where the Sport Maxx race 2. N1 was homologated for 981 GT4, 718 GT4. N2 for 981 GT4, 718 GT4 and 718 GT4RS. Based on production codes floating around it looks like Dunlop stopped N1 production sometime in 2021.
Perfect - thanks for confirming
