will bigger tires raise the top speed?

 

[Zeus]

Hypothetically, yes. Bigger tires, not wider ones, should raise the top speed. It may also lower your acceleration, and I'm not sure that the difference would be very substantial.

Also keep in mind the weight of the tires. All in all any aftermarket radial tire 26"-28" is a improvement.

I just put 26's on my Pioneer, today. Honestly, the idea of gaining top-end speed never entered into the process.

Just for S's&G's.....what are you trying to achieve?

 

[kgrant1965]

i was pretty sure taller tires would raise the top end i just don't know how to calculate it

 

[rich450es]

if i can voice a opinion on this ...... the best way to see how fast you are going when you change tire size is to check it on youre smart phone (GPS ) or have a buddy get along side of you in his truck or car and when you stop going faster have him read his spedo .... im sure you could also run it on a dyno also

 

[Kyhunter]

It'll possibly give you 2 or 3 mph

Gps +1

On flat ground with clear skies(no tree limbs) A standard GPS should be plenty accurate over a short distance.(+ or - .1 - .2mph) Where I work we can get centimeter level accuracy with the latest GPS's

I have 27" silverback xlites on 12" ss 212 rims and I can't hit the rev limiter anymore. Speedo read 41 when i topped out . On stock tires it would run 45 on the speedo and hit the limiter . I'll try it again with a GPS if I get a chance this weekend .

Speedo is now off. Same thing happens when you put bigger tires on a truck.

i am going to put 27 inch tires on the factory rims will this help better when climbing hills. i know it might slow it down some but i dont mind that if the climbing is better and handling.

 

[kgrant1965]

I am thinking 26 inch maxxis ceros tires anybody use them? Also I bought some brand new itp ss 216 wheels from a guy for 200.00 will they work? I hope so lol

I'm pretty sure it would be off going from 25" to 27" but my point was I don't have the hp to hit the limiter with the bigger tires on and I'm pretty sure I didn't gain any top end speed but didn't have a GPS to confirm that. I read on here someone put 27 executioners on and said they hit the limiter at 45. That wasn't the case with me. Could be the difference of a single smaller person vs two ( one very large ) and a cooler. Ill have to put the wife on a diet and try again. Anyone else with 27" or 28" tires hitting the rev limiter?

 

[CSFI]

I can easily hit the limiter with 28" Bighorns

Well that's it she's going to the gym for sure now.

What did your speedo read when it hit the limiter with the 28" tires?

 

[skorp1702]

26-46 mph. 27-48 mph 28-50mph. Weight needs to be low I have 27s and can only get 47 on gps. I have a spreadsheet I wrote for tire speeds versus stock and input tire height

 

[adnoh]

Skorp you were still able to hit the rev limiter correct? Thats starting to concern me as others are also having no problem getting there. Mine had alot of pedal left but was just flat. I didnt feel like I was even close to getting there. Ill give it another run with just me in it and see what happens before I get to worked up about it.

 

[skorp1702]

On hard pack dirt yes I can hit the rev limiter on a dirt gravel rd around 41-43 on the speedo depending on the road

 

[binfordw]

You could do the math, assuming you know the actual tire diameters.

 

[skorp1702]

Binford look at my 2nd to last post thats limiter for sizes
