[1985GN]

ok guys im in need of a new tires but with all the new stuff my car has i think im gonna run out of steam up top with a 26" tgall nitto DR? right now i have the combo below and i ahve since added a mease DP. when i play around on the street and all at the top of the quarter it seems to run otu of pull since its revving so high. i went to the track not to long ago and with a shot 2-3 shift i did 87mph and some change in the 1/8 without the DP and 19psi of boost. should i just go to a 28" tall tire or stick with a 26"? i plan on turning up the wick on the car and tuning it soon. let me know waht you guys think i should get. thanks

I think 28" tires will work best Frank
