I am in the market to buy some drag radials again. Last year i bought 17in 275/40 Nittos DR's and the best i could pull for a 60 ft was 1.91 with my 4.10s. If i go to say a weld rim and a 15in DR with 275/40s will i be able to cut a better 60 ft, or do i just need to practice my driving on my 17's? If i do the 15s i will need to buy some rims but i dont want to spend to much money. What should i do?
