No you could but I think you are going to really have to work on the setup to make that work. It would be better to just run the same all the way around. Im not sure what the temp rating is between the D's and Pro's if they are too far apart you will have a car that will handle different as the tires heat up.

If you were using the same compound I would think they would work just fine given they are both the same dia. What compound x patterns were you using?

This tire game for the perfect setup should be eliminated before it continues any further. One tire, one compound (or a choice of compounds) and be done with it. This mixing and matching for the "optimal combination" is a deadly path.

Just look at the tire boxes of off road racers to see where that problem leads. This conversation is already making me not want to run USGT.

In this case, I agree 100%. There was nothing 'broken' with the choice of HPI X pattern tires (3 choices) that needed fixing.

"Simple and effective" should be the hallmark of RCGT, just like VTA.

The X-patterns are a really good tire, offered in the same compound as USVTA racers have been using for 3-4 years, and a slightly softer "pro" compound. They are 26mm wide, which fit a myriad wheels in offsets that allow for both 190mm and 200mm bodies, and they are in plentiful supply. If they aren't and they are used by everyone, HPI will ramp up production just like they did for VTA vintage tires.

These are the kinds of simple structures and rules that would head off the racer's inherent tendencies to look for that last little advantage before they ever hit the track—and cause people to spend more than they normally would if everyone was using the same thing.

what type of run time am I looking at with a 3200mAh 2c lipo with a novak havoc 21.5 assuming it's a fairly large outdoor track?

I made a huge investment when I was in the hobby years ago buying 2 6000mAh lipos, a charger, and a lot of brushless gear but none of it meets USGT standards (with good reason) so I'm back to the drawing boards...would this setup suffice? Would the difference between an og maxamps 6000mAh lipo and a 30c 3200mAh hard case be big enough that I should be practicing on the regulation packs? At $55 a piece I shouldn't be complaining after my originals were $120 but I'm trying to keep the hobby cheaper this time around (I'm even sticking to one car instead of 10!).

It would depend on your gearing and other factors but I would think with a 3200mah pack you should be able to get about 10 to 12 minutes of run time. I was running my car this past weekend for 8 minutes and only taking about 1000-1200mah out of the pack. I would think between the two types of packs you will just see more runtime between them.

I know that a properly setup GT Car with the Right HPI tires has as much grip as a set of race slicks... As far as the tires are concerned... this is really the breakdown for me

HPI = Most scale looking, 3 choices of rubber, most expensive, and have to build them, your looking at 40 bucks between the tires, rim and glue.. Wear is all over the place, our track I can get months of running from a set, at other places.. One set a race day. But you CANNOT beat the SCALE look of these.. they are simply awesome....

Again to not run into a potential situation where "the only 1 spec tire" happens to be "out" and no one can run the class. As far as wheels are concerned I have from the beginning always made it open to any realistic 26mm wheels.

I hope that I've answered some questions and shed some light on the concept of RCGT.

Thank you,

We do not have that issue at our track or most others, but at the same time, we could find a MUCH MORE cost effect situation. just something to think about.
This is some of the stuff that informed the current tire rule. At this point, the rule is definitely not final. However, there seemed to be plenty of complaints about the X patterns, mostly centering around wear vs. the price.
Availability issues are very secondary, but still there.

To be honest, I would consider specing these 3 tires:
http://www.integy.com/st_prod.html?p...=714&p_catid=4
http://www.integy.com/st_prod.html?p...=715&p_catid=4
http://www.integy.com/st_prod.html?p...=716&p_catid=4

The price is unreal, and so far they work great on carpet. If they are ok on asphalt, it would be a great deal.

EXCEPT that Integy supply, distribution, and online response is NOTORIOUSLY poor.

The further that you get from a product that is already widely and easily distributed, and already on shelves, the more problems you're going to have.

As it is, that post of yours just sparked a spike in orders to Integy's web site! Probably take about a week or so for them to be out of stock.....and never come back......then we're back to square one (HPI X patterns).

Let's not even get into the debate about "Which inserts are best?" that comes with going with loose donuts! That only leads to spec'ing inserts, as well.

I guess i will keep the rules the same so I can buy $3 tires.

You may purchase HPI if you wish.

The inserts are speced as well - open cell foam.

The other thing is, do you not think I would contact Integy to see what they expect for a supply on those tires?

Rob, since I was quoted in your earlier post, let me put that comment in the right context. I am a supporter of the HPI X-pattern tires. Yes, they aren't the cheapest and yes, I have seen terrible wear.....BUT, availability has always been good and, as a 26mm tire choice it works with 26mm offset wheel choices which I believe should be part of the equation. Tire wear is , and will always be, dependent on many factors. Most of the wear issues are due to newer drivers with lesser setup knowledge and the fact that they tend to go run the car for 30 minute bash sessions without checking tire wear.
That being said, I believe offering 2 tire choices of 26mm and a similar counterpart in 24mm is a sound concept. The X Pattern and the Solaris seem to be good choices with a minimum of concessions.

Glad to see the tire debate continuing in earnest here, as we're still going through the same thing, and it's the last hurdle to having a solid, unified class. All of the other aspects of the spec have been spot-on (21.5 spec/GT bodies & wings/etc.). We're at the point where we're getting 20-25 racers, but they're still split into two camps: X-Pattern and Solaris premount.

The pace is about the same. Solaris users enjoy simplicity, grip, longevity, affordability and decent looks at the expense of variety and uber-cool rims. X-Pattern users enjoy 3 tire and infinite insert choices, perfect scale looks, and different offsets to fill out 200mm bodies at the expense of price, labor, and wear.

At this point we're kind of at an impasse. Perhaps a nationally-unified ruling would sway us to one side, although many seem to have a religious fervor for their preference.

Personally, I like the Solaris option, but I'd jump ship if it meant we could all run the same thing and not split up the class.
