Is a 33 inch offroad tire taller then a highway 235-85 ?? were just tryin to get more top speed, drag racing with our no overdrive.

 

yes, iirc a 235/85 is around 31" tall.

 

Yeah 285's are 33's.good luck.Ezra

 

255/85-16s

 

Yes ! 255/85 is taller and skinnier and you may be able to find a tread that is smooth adn won't bog you down, especially for drag racing... forget the knobby tires! my 245/70R19.5 tires are 33.6" ...tall and skinny.

 

If anyone knows of any 255/85-16's that are E range or different from these please post:
BFG Mud terrain
Toy M-55
Cooper and Dunlop(Both I think are D range)

 

Actually they would be considered a 32" tire.

285/75 yes.

 

The formula for figuring out the height of a tire is simple. Width X Side wall ratio (ie. 70 or 75 or 80 series sidewall) X 2 (top and bottom sidewall/tire) + the size of the rim. So for example a tire such as a 235/85/16 would be:

235mm X .85 X 2 + 16inches = 31.98inches

The tire width is in millimeters (235mm) so we have to convert that to inches which is simply divide by 10 (convert to centimeters) then divide by 2.5.(to get inches)

so again a 255/85/16 would be:

255mm = 10.2" so 10.2 X .85 X 2 + 16 = 33.34inches

 

Also remember i dont care about width. im looking for a taller tire than a 235-85... SO I CAN GET MORE TOP SPEED IN THE 1/4 MILE. thats why i want taller tires. but race is at e-town on sunday and im like out of time to get taller tires. the 33's i have here are too wide. they will slow me down. and there like groundhawg tread. that will REALLY slow me down.
