Tire Sizes

[EmiraMike53]

What size tires is everyone running? Anyone upsized from stock? I have the GRP Y10 wheels coming so I’m looking for options. Trackable street tires.

Thanks

The only real upsize that would work would be a 255/35 R20 and a 305/30 R20. Those would each be 2/10's of an inch bigger in over diameter over the stock setup. Anything wider would have to come down in profile. For instance, a 325/25 would be 6/10' of an inch smaller than stock. That is a decent amount of down-sizing. That tire would also need an 11 or 11.5" wheel to work well. 11" will easily fit the Emira, but you would have to check backspacing (brakes/suspension) to see if an 11.5" would work. My best guess is that it would, but you would need to be around +18mm poke from factory set and may need another degree of camber.

This is ALL assuming you are sticking with a 20" wheel.

I am contemplating having a set built as such:
20x9 et50 with 255/35 R20 Tires
20x11 et45 with 305/30 R20 Tires

Thanks Mr. Wolfe! Great info!

295 is already a big tire on a 10.5 wheel - any bigger is too big unless you go aftermarket to 11. Emira doesn't have a traction problem though so not sure of the point

Some people just like the look of a wider tire. No different than preferring blue over yellow.

No issue with that - it's personal preference at the end of the day. But also worth you watching this where Russel Carr talks about how careful and selective they were about the tyres they used on the Emira for best handling.
