I am guessing this is an old debate but. What is the better tire mount a 23mm hex or square like some of the 1/5ths have. My local hs only has 17 and 23mm hexes on the shelf and they suck to order anything. Besides if I'm going to order I might as well do it online. The 23 mm are beadlock series 40, big$$$.

I'm looking for a reasonable price tire rim setup for my car and can setup anything I want. Just trying to figure out what all my options are. Being new to all this I'm not sure what all my options are. I may end using a tire and rim setup from something like a hand truck but then I have no choice in tread pattern.[link]http://www.harborfreightusa.com/usa/itemdisplay/displayItem.do?itemid=30900[/link][link]http://www.harborfreightusa.com/usa/itemdisplay/displayItem.do?itemid=41475[/link]

is this for a baja or a fg car? the problem with 1/10 scale tires they dont last long.

Bigger tires cause more problems for a little motor. Proper gearing is need to move big things.

Part-time : It is for a homemade car eventually 4 wheel drive. Trying to figure my best route of attack so I don't do the axles twice.

bsrman : yes tire size is important for the gearing but motor size (no spec on hp, torque, or rpm)makes no difference for this question..As you well know engines are not 1 flavor of these specs for a given displacement just running gasoline or alchohol makes a huge difference.. For all you know I want a stump puller with max speed of 2mph. If you care to push this again then answer the questions in the other post until then - me and you(bsrman) are DONE !

I think the HPI Baja wheel might do the trick. Easy to get and the shaft size is pretty thick. Let me know if you need an engine I have a new Smartech I can sell cheap! Great for a project car.

Well if 23 mm will work for ya then go for it..What do you have for the most wheel and tire choice's on after market for what you
want to do with your project?..Your engine can turn any wheel combo you want..just what do you want to get for your application
better traction, driffting guess depends on what you want to use you RC unit for..and how you many drive it..
As for wheel adapters there is pro and con on this ..hex or squares..I would think you have better choice with the hex for you
choice of wheel rims too use..AKASlawhammer

I gave you all the info. How you used it is your problem but you didn't get the same numbers as me.
I have provn that RPM is usless in figureing max speed when HP is the most important part of the problem. YOU see you failed to get it. NOw your doing exactly what I knew you would do again. If you want a stump puller Great but unless you gear it right it won't get the job done. With 1 hp you won't get get the same results as if you used a 3 hp motor same RPM. I know this for a fact you won't. More hp more power and speed. Less hp less power and speed.
It's all about the hp and gearing.

Bsrman is correct on the gearing and horsepower...I have a nitro puller for sleds...Power Gearing and Tires...
I may do a power sled truck for gas...AKASlawhammer

Selwa: Thanks I currently have 23mm hexes and I noticed I am starting to spin the hex out of the rim. I'm not sure how much stronger the squares would be.

Slaw: Mainly offroad but will have times of onroad. What kind of rim/tire combo's do you run on a puller? I went to the 23 mm hexes from 14 with 17mm adapters after spinning them out and now a similiar issue with the 23's.
I know bsrman is correct on gearing BUT all he does is say this or that but cannot support his thoughts so I am DONE with him until he shares some hard proof. At one point he told me that with my ratio I would have to push start the car to get 35mph couldn't be farther from the truth. Also that the engine rpm has no impact on top speed.

After looking at your pictures I can see you would strip and tear things up with the power plant you have now for the small parts you are using..
For your project you have done well for what you have made...I am not builder by any means..Just a old retired
auto mechanic after 45 years in the trade...I have had 4x4's and motorcycles in between.. Now as to you wheels you may have to go to square drive ..cuz right angles
are always stronger...So with that in mind ..you will want to look for wheels with square drive holes and tires I am not sure of that my self..
As I am some what still new to this 1/5 scale my self...I don't want to steer you in the wrong direction on that..Better to ask more questions..

I gave you the proof and you couldn't use it because you kept using RPM for caculations. It didn't work proven by SOLO. The only reason your gearing worked the first time was because you were close but still over geared. Proven by you with the clutch not fully engaged with the clutch getting hot. Smaller tires will spin faster than larger tires. With 1 hp you will have too gear it differently+ with 4x4 more gearing. A simple 3.5 :1 won't work with 10" tires. Untill you prove to me what my ratio is. I will then post a picture of the actual gearing to prove it. I gave you all the information.

thanks for the support slawhammer. Someone gets it.
