When the vehicle in question is only going to do 3mph, cut'n'shut tyres are all well and good. I would never recommend this construction technique for speed tyres. Unless you really like to see spectacular crashes.




It's true to say that, for a given construction, the bigger the tyre, the higher the rotating mass and that this will reduce the power available to propel the vehicle forward. It's not true to say that big tyres are bad. There is a trade-off and it's therefore reasonable to assume that there is a "sweet spot" somewhere along the continuum between 2" and 8". Where that sweet spot is will depend on the construction of the tyre and wheel. Foam tyres are generally far lighter than standard rubber and so the sweet spot will tend towards the larger sizes. That said, let us remember that the fastest E-Revo so far, used 5 1/2" tyres.



You did "the speed thing"? Perhaps you'd be willing to share your performance. Just because you never got anywhere with larger tyres doesn't persuade me unless you're going to substantiate your opinion with facts.



Well, I certainly congratulate you on learning a new word. It pays to enrich your word power. However, knowing words isn't everything. You need to know how to put them in an order that reflects what's going on in your head. I suggest you practice that. As for the name calling, it now becomes clear to me why you were defending Brian's post. You think insulting strangers is acceptable. Well, let's hope you don't insult some one who's carrying a gun. Oh! And before you descend into a tirade involving statements about my Mother, I'm immune to such attempts as these really only work on Americans.

No thank you.
