i have a nitro evader st and as my stock tires are finally starting to wear down im wondering if i should get a set of pro-line mashers. is there any difference in the speed or handling? better or worse than the stock ones? any help will be greatly appreciated.[8D]

what are you planing on running your truck on

Both worse, speed will go down, and handling will not be as good.

You will have to change your gearing most likely to lower gearing to compensate for the bigger tires but the biggger tire are also heavier so after you gear it right to gain back the accel. you might loose a litlle speed, depends on how powerfull you engine is, I have a set on my rustler with OS .18 and the handling isnt as good it doesnt grip as hard in turns, and if you have your ride height set pretty high I role my car quite often. But if your using them for bashing I love them over stock tires or small tires, they moab over everything.

im just going to be using them for bashing at a park near my house. so its pretty much just grass and dirt.

Mashers would be a good choice then

thats what i was thinking, but im wondering exactly why?[&:]

One part of this is true the other is wrong ,
I have a set for my Rusty , a bigger tire will give you higher speed but they don't do anything for handleing. You don't need to use a foam liner in them however they might add a bit of stifness to the side walls

is that why they dont come with a foam insert? i just find that a little strange that they dont need them.

Ya dude that would be why

A larger tire can give higher speed, but only if your engine has enough torque to turn them at the same RPM as smaller tires with the same gearing. In most cases this is not possible, lower gearing will be required to maintain the same performance (acceleration) and your speed will either stay about the same or go down.

BUNK[>:] I've not changed a thing exept tires and gained speed over smaller tires. Not gears , not nothing . the only thing that would make any differnce at all would be if the mashers were to by significantly heavyer then the tires that were previously on

i think their about the same weight as the stock tires if not just a little more. and torque? i have no issue in that department with the .18 im running. sometimes its almost like it has too much torque...

jakjr may be a mod. for these forurms but that dose not mean he is always correct . To end all this I say just get a set . they should be just fine for what you want to use them for
Sorry if I jerked anyones chain.

Maybe with nitro it's different, I'm no nitro guru myself, but I know for a fact it is exactly as I said with electric cars.

Uh.......... ok , physics do't lie . you my what to look into it

A bigger tire will NOT automatically give you higher speed. Whether it's electric or nitro. The larger tire has a signifigantly larger roll-out, as well as more mass. It will require additional torque to get the wheel moving, over a smaller sized tire. You will have to compensate for the additional roll-out by adjusting your gear ratio. By doing so, you will lose top speed. The rotating mass of the tire will also reduce to overall speed of the vehicle.

The other consideration is tire ballooning. The M2k's are very soft, and very large and prone to balloon under power. This will further reduce the efficiency of the tire, and reduce to overall top speed. As you said, physics don't lie. All a larger tire will do is overload your engine, and cause heating issues, and premature failure. If you want to go fast, you want smaller diameter tires, with a lower final drive ratio.

If you haven't changed your gear ratio's, I can tell you this: Yes your truck is faster. But it takes longer to accelerate, your runtime is probably only about 9 minutes, and your cylinder head temp is probably in excess of 240*f after a run. You can run it like that, but not for very long!

Have you not understood a word I've said ? If the masher is NOT heavier then it will not take any more power to get it rolling. He has said TOURQUE is not an isue so no need for additional gearing is required. As for ballooning....Yes they do tend to do that and as they do so that increases roll out increasing speed even more . TRUE this will do not a thing to improve handling
are we done now ????

You say the mashers are not heavier than a racing style tire, therefore you must have weighed them on a precision scale, so how about posting the weight of a masher compared to a racing style tire for us? This should not be a problem for you as you have made it very clear that you must have at one time accurately weighed them to know that they are not any heavier.

Torque may not be an issue, but what about the acceleration? Mark off 100' out in the road and take GPS speed measurements (or time it with a stopwatch) using mashers then using racing style tires, then tell me you do not need to adjust gearing to maintain the same acceleration.

A highly ballooned tire with have a smaller contact patch (therefore more traction loss), and increased wind resistance. Just because the roll out is longer does not necessarily mean that it willl make for a higher top speed.

MT tires on an ST is a formula for clumsy handling. It's too much tire. Mashers are good in mud, but pretty lousy on anything else.

[>:] DUDE !!! I did NOT say they are heavier. I said > IF < they are. Acceleration is not the isue here . It is will a larger diameter tire run faster ?
Now....... As for ballooning . Back to simple physics larger tire = higher speed. When it's running at full tilt.
READ , PAY ATENTION , LEARN [>:] These fourms are her to help each other . I have not lived for almost 46 years and learned as little as you my think. If you feel I am so stupid then shut down my part in this thred . I'm DONE with it any way

wow, i didnt mean for it to turn into THIS. i just wanted pros and cons. maybe ill just get some pro-line bow ties again. sorry guys.[&o]

No need to say sorry . I'm the guy that will say that. I just don't care to be made to look like I'm stupid . Even if I can't spell to good Give the Mashers a try I think you may like them.

Sorry my mistake, I did not read that correctly [8|


It's obvious neither of us are going to change the others idea on this, and I have more important things to do than debate about something as boring as this, so lets just forget about it.

I'm not pointing a finger at anyone here but this reminds me of something my father told me when I was little : If I'm not 100% sure of what I'm talking about I'll keep my mouth shut and let folks think I'm stupid then open it and prove them right : Wise words , Thanks for that lesson dad
