My G2s wouldn't hold at all, sideways Jonesing thru 2nd gear.

What do you guys think about just going with the stock size NT555RII
275/35R20

Do you think they’d give up a lot of traction at this power level?
They are a bit shorter and narrower

I imagine the 305s look better tho. Do you have any pics of it?

275/35/20 is stock size...either way I would get the 305...it fits fine, looks fine, and works great. Been running them for years now.

Also 29 psi won't give you full traction. They need to be down around 23psi for full send mode.

Nice pic. First time I've seen your car.

Thanks! Yeah I am old school. I still like chrome and a beefy tire outback.

305 35 20 on 9.5 stock wheel and my car is lowered on Phastek springs. I love the look of the big tire on the rear. It tucks right up under the wells.

Looks good..and that back drop

I have them in my cart on jegs. Hopefully I can move move my 17s and the extra parts I have laying around lol

You sure do. When you getting to the track again?

Ordered NT555R2s in 305/30/20 to go on my 20x11s. I can vouch that the NT05s were a poor choice. The 555R2s are back ordered for a month or so.

WWT has no drag events, at least no WOW or MM until July. Prob still cleaning up from the Enjoy Illinois 300. So will get back after they open and when I've got my new tires. I might try a few runs with the NT05s and then the 555R2s. I like comparing small changes to see the difference. Between last time and the next time out I'll have the Trans tune, converter, and DS different already.
