Once my current set is worn, Im going bigger, just not sure how.


I currently have 235/60/15's they are 26.1" tall 8.4 wide (the actual tread touching the road)

I have two choices, ether the much larger contact with the road, and same height:
275/50/15 26.1" tall 10.5 wide

or the little bit wider, but a tiny bit taller, which will give a a good final drive gear ratio for the track
255/60/15 27.1" tall 9.0 wide

thoughts?

 

275's

 

275 / 60 / 15

 

/\ looking good!

I know the 275's will give me more grip out of the hole, but im worried that my gears will be to steep on the bottle.

 

Youll still be ok even when running the bottle 275's all the way!

 

with my trap speed on the bottle, ill be right on the OEM rpm limiter. I dont like that at all.

 

I had the same issues and went to a taller tire, these when heated up stick pretty good actually really good. I just put a set of Billets and Hoosier 17 DOT for this coming season, should be interesting.

Note, with the taller bigger tire you must roll the inner fender and beat the inner well to fit and most important, springs! If you have an anti roll bar you are golden.

 

good to hear, but I have stock stuff in the rear other then shocks and control arms.

doing the math, I will be at 5900rpm crossing the 1/4 mile. My issue has been using the stock tach, what I thought was 6,000 rpm, was probably more like 5200 by the looks of this gear ratio calculator im using.


now I need to buy a aftermarket tach!


thanks guys, I think ill go with the 275/50/15

 

BTW here is the "Green Hornet" just completed today! All new trim

 

sweeet, what all did you get done?

I hope your not hitting the drag strip with those rims..

or did they do a 5lug swap too?
