In my opinion, tires are much more than a rubber part that we can put on a rim in the hope they will do the job, I think tires designers have reach over the years, such a level of performance and tecnologies, which is now at the state of the art of development. So let's talk about tires secrets and functionalities. One of the question that comes up most often in people's minds is... what is the best tire but the real question could be, what is the best tire that will match the surface or track condition, however the goal here is not to respond to this impossible question but it's to provide some adequates informations to make things clear enough that I hope people will be able to choose the right tire that will provide the best performance in a given condition.

Bashing tires

Most of the time the obvious suggest to go with an all terrain tire but as you know there are so many, it's like trying to setup the combination of a padlock without knowing the numbers. Ok to make things clear and as simple as possible, there are many kinds of tires patterns, or tread style if you prefer, however we can regroup them all in three categories, the first one has some longitudinal tire pattern, which is parallel to the sense of rotation and those tires will offer the most possible lateral grip and are intended to be used in the front only, the second category owns multiple lateral treads style, it's what we call a traction tire and for a 2WD or 4WD vehicle it's ideally utilised on the rear setup, it will permit to have the most traction capacity with more braking efficicency, also it allows the rear to drift a little bit, which is a good thing in most cases, especially to help correcting the Rustler understeer features, therefore the last one is a tire with some dispersed rectangular or square fashion treading and the fact is that it could be install on the four wheels but on some type of 4WD and / or on most soft surfaces, sometimes it is better used for the front setup application, the general idea here, is to avoid to lock the slide capacity of the rear end, yes the reality is that if we decrease the slide rear ability of a vehicle and we increase rear tires grip, then the front wheels will slip during high speed or hard cornering and this effect is called understeer, so in an off road use, to be in control with a good front handling capacity, we really need a tire setup who will offer some oversteer.

Knobs size and length

Before starting here I have to stipulate that it's also possible to regroup terrain surfaces in three categories, we have soft / medium soft and hard surfaces. Beside the fact that tires own different knobs shape there are also many knobs size and length, what does all that means..? Ok generaly, long length knobs tires will work better on medium and soft surfaces but the question is, what should be the traction and grip effect with smaller diameter long length knobs tire VS a tire who has a bigger long knobs pattern and the answer is simple as the one with smaller long length knobs is more indented to be used in a medium soft surface, because it has more digging capacity and the bigger diameter long knobs tires provides a little more traction and grip on loose surfaces. Now the only remaning one is the short knobs tire, that sometimes is called race tire, first we have to know that most race tracks are constituated with hard packed or carpet surfaces and the reasons for that, it's because it requires less track maintenance and with the apropriate tire, hard or carpeted tracks will offer much more traction and grip than loose surfaces tracks, so the best setup we can expect here, is a ribbed tire or a longitudinal tread style on front and a short with many regrouped knobs pattern for the rear end.

Tires compound

Sometimes with some type of manufacturers it's possible to choose the tires compound and normally softer the ruber is, better the traction and handling they will provide but this is a valuable rule with race tires only, however oftentime with a long length knobs bashing tire, the ruber compound is so soft that the knobs will flex to a point that it could lose some overrall traction and handling efficency and the fact that they are soft makes that, the tire will work well for the first week or so, then when the knobs start to round down, they could lose a good part of their traction and grip capacities but this condition is mostly observable when tires are used on surfaces for which they are not designed to be used on, on the other hand it's possible to have a hard made tire but the part of plastic who is mix with the rubber is so high that the tire will spin more, consequently it could offer less traction and handling, also because it will spin more than it should, it could wear out faster. In conclusion, a medium compound tire could offer better overall traction and handling with more durability, it could also be used on more varieties of surfaces.

2.2 vs 2.8 tires

It almost appears that some of us are born with the idea in mind that bigger is better but prove me wrong that 2.8 tires could offer some advantages over the 2.2 setup. Arrogance and conceptual ignorance constraints, the dark side are they, depending on which side of the force you are, forever 2.8 tires will dominate your fate, no seriousely, if we look with the light side of the reality, we are forced to admit that the 2.2 tires offer the same wideness but they are lighter and lower, so it permits a lower center of gravity and when we change tires size, consequently the wheels ratio changes, that means bigger tires will cover more distance in one rotation than smaller one and like changing gears ratio, the car speed will increase but for some reasons the effect on handling and acceleration are reduced, also with a higher COG during acceleration the weight transfer to the rear is increased and that is a realy bad thing, it tends to annihilate the slide effect ability of the rear end as well than release some of the front end tires pressure to the ground, so needless to say which effect all that will induce and if we add to the fact that 2.8 tires are also heavier, the motor will have more weight and a heavier rotating mass to put in motion, here we have two downsides that will tend to increase ESC and motor temperature as well as the durability of those components but with a 2.2 tires setting, the motor has less inertia to put in motion, so the demand for energy is less and with a 5000 mah battery, the autonomy is increased by about 50%, effectively with the stock gearing, if we could make a run of about 15 to 20 minutes, then with the 2.2 it should be possible to double the running time, therefore if we start from the principle that we use a battery pack 10 time a week, then it could double the running time. Now if we run on a 2.2 setup and we charge the same pack only 5 times a week, we should say, that could give about the same overall autonomy but in theory this should double batteries durability.

Once we find the padlock numbers, now it's time to open the drawer of ignorance, in the hope that we could feed it with some knowledge, but like my father always said, even the best knowledge in the world, is just as good as the one who applicates it..★
