I need some advice. I am wanting to get some drag radials to mount on some stock 16" aluminum wheels I recently picked up. My truck is putting out about 300hp and 320 ft/lbs (dyno) and was hooking up pretty good with the stock 20s at the track last weekend. 60' times were right around 2.20 sec. I still have the stock 'verter with no plans to update it for a year or so. What do you think? Should I go with 26" diameter or 28" diameter drag radials?

I would run the 26" drag radials to help with the gearing especially with a stock converter.With 28" and a stock converter you'd probably bog out of the hole due to no wheelspin.What gears are you running?

I have 3.73 gears and my tire height is 31" or so.

26" is really short. It's going to look very odd. Even the 28's are small. Keep in mind that the larger the diameter the tire is the better traction you can get off the line because more rubber to concrete contact is made, but the smaller tires will give the axles better leverage to get the truck moving. The smaller tires will net you a quicker 60-foot time if you can get them to hook up. Personally I would choose the 28" ones just based on looks. 26" would look a little too SotB for my taste.

The 26" tires might look funny but the increase in gearing will make a considerable difference in accelaration after the 60' mark.With 26" tires he will cross the 1/4mile line pulling hard in 3rd gear instead of struggling to reach the powerband in 3rd.Besides,I doubt his drag radials will be used on the street.

i would go with the 26" tall drag radials, like everyone else says, it will help your gearing to get out of the hole.

2wd.

With either size drag radial you will see an increase in gearing.What that does is increase the average hp produced by the engine during your 1/4th mile run by keeping the engine in the powerband a higher percentage of the time.You will see a reduction in your 60' times due to the increased traction of the tire compounds as well as increase mechanical force applied due to the decreased tire diameter.Going to a smaller diameter tire lets you increase your gearing at the track without paying a penalty in increased fuel consumtion on the street.

I saw an old POS ford v6 truck at the track with passanger tires on the rear running 16s. Cheaper than gears, looks goofy as hell though. Will 26in DR really give you enough traction???
