If I cut a 2.0 60' with 265/65/18 and a stock 3.42what can I exspect with drag radials and a 4.10s.

 

A little better probably.

Seriously though, its impossible to give you solid answer. It depends heavily on your suspension, the track properties that day, and a little luck.

 

Slicks are 100% more forgiving for sure. I haven’t dialed the suspension in the back of my car yet, but I was coming off the t brake at 4500rpm on a 9x28 M/T slick, and it spun very little, ran a 1.51 sixty, 10.49@131mph. This year, tried the same launching with 295/55R15 M/T street radials. It would grenade the tires, pedal it to a 1.81, tried it at 3000rpm, same thing. Unhooked my t brake, and just used the two step at 3000rpm and the foot brake, the radial went 1.51 sixty 10.44@129mph (dirty air cleaner I found later, that’s why I was dropping mph)

So, all sorted out on a slick, I expect it to go 1.3X off the brake whipping it hard. I bet the radial won’t be far behind though. There are guys going WAY faster than me in the 60’ on radials. It just depends what you’re set up for, and track conditions. Slicks will compensate for track conditions varying better, but they aren’t necessarily better. If you are driving to the track on them, My vote is radials. They do last longer from my experience. If you don’t have any suspension aids yet my vote is Smith Racecraft Assassin bars, and Calvert racing mono leafs. Get the truck as low as you can stand to help your "instant center" for lack of a better term (it isn't instantaneous on a leaf spring or ladder bar vehicle) out as much as you can.

Wasnt thinking when i wrote the post. Lol. I understand now. i was looking at m/t et Street radails and I could only find 255/50/16 26×10.5 16. What would be a good tire size. I have have been doing alot of studying on tires. It seems there are so many variables size, psi, some like alot of heat some some dont need to be as hot. So Im going to have to pull the trigger on something and see whats good for my setup.

 

if you have a hot rod truck a radial will be plenty of bite. If you have a HP monster like past 500 wheel then a slick would be my choice, esp if you are 2wd. its a no brainer.

I have played on a few diff radials and a few dif slicks with my ol mustang ( 900 ft tq ). Radials were def more smooth cruising and at high speed but when i mashed the gas I wanted the car to hook so slicks it was. I ended up liking the hoosiers et drag. they fit great and really hooked up amazing. of course they have a little wobble when cruisng around town and especially on crappy roads and a tiny bit of bounce at 145 traps. But again most guys in here have trucks with decent power but arent in that hp/trap range.

if you already have caltracks, id say put the biggest ( tallest and widest ) MT et street on your truck and have fun. It will hook.

 

Lol ok.

 

I think I seen 28 11.5 16. Wil they fit n a 16×7 rim?

 

I would want at least a 8.5 wheel for that...preferably a 10". You want as much contact path as possible.

 

Yeah. Right now. Trying to decide. But just going to go with 255/50/16. For now. But I will be trying to get a 15 on the old truck I found so many 15 slicks, drag radials. For cheap drand new on craigslist its not even funny.

 

you can put a slick on anything and it will hook even with little to no prep and how ever much power you are making.

drag radials need a well tuned chassis, a good driver and good prep.
once the tires start spinning on DRs you are screwed.
