Drag Race Tire Tech:The FASTEST Way to Change your Gear Ratio! #nonamenationals #DragSlicks #Mopar

With a testing session coming up for my 68 Plymouth BARRACUDA drag car, I have recently swapped DRAG SLICKS that have a different diameter. I give you a quick and simple formula to calculate your new final Gear ratio(Effective Gear Ratio) when switching tire sizes!

Very well done. Very well explained. Great job!

[moparnut]

This is the math they should have taught me in school then I would've payed attention!!

[musclecarmitch]

Great information! Difference in two tires that should be the same could really cause problems! I've always took for granted that two of the same brand would be the same and now I know they may not be! Thanks for sharing the formula and this information Joe!

I just changed from the stock single leg 3:55 to the trac-lock with 3:90 huge difference!!! Great Video as always!!

Excellent video!! So many over look the simple things such as this. Tire growth at speed is something else to factor in

[drcracinggarage]

Some people don't realize how important the little things are

[edsmachine]

Very good topic.
A close look into how and why's.
Great job Joe.
I would like to give your video 5 thumbs up on this subject. 👍 👍👍👍👍
Great content.
Thank you, Ed.

Good video my man. Glad we are already at a 26” tire. We went from a 60 series front tire to a 50 and you will see soon how that helped with rollout on the line

[HacksGarage]

Awesome video man!!! Tires make a HUGE difference !

[BigMikesHooptyBarn]

Thanks Joe. I probably won't be getting into the fine tuned aspects of drag racing any time soon but I know who to hit up when I do!

[donaldhalls]

That's a good explanation and examples, all the best to you and your loved ones

[approachingtarget.]

Effective ratio..that is correct. Good Info.
Final gear ratio...or the gear ratio when the tire is squatting can change drastically with as little as 2psi of change. A hard planting suspension and low tire pressure can cause your effective gear ratio to change 2 full points. Changing your tire diameter up too 10 inches.

My brain adjusted & was able to pick it up lol . Very detailed imput. I shall roll with the 26.1 & 3.55 Drag radials. I appreciate it💨

I had a set of slicks that were the same exact tires bought at the o time. One was little bigger. I had to run more air in one to make them the same. Because the front end jumped to one side a little when I launched it

[asspin]

Good schooling, thanks Joe, take care.👍👍👍

[robertmagni]

Thanks Joe now I know how to figure out my effective ratio I went from 235/70-15 to 275/60-15 Mickey Thompson tires with a 3.90 rear gear stock was a 3.22 gear

Great video Joe. Lots of people don't think of the effect if tire size on gear ratio.

MOPAR Joe kill'n it!!! Thanks for the great see that 400 big block build brother 💯😎

[timosracecars]
