› GRP GTX02 Slick Tires
Get the grip you need on any on-road surface
GRP is a tire company based in Europe that has been in business since 1994. Since then GRP has become the go-to tire for many racers around the world. You can get many of GRP’S on-road tires in the United States through Hobby Heroes: 1/10-scale slicks, 1/5-scale treaded on-road tires, various colors of spoked wheels, and more.
The GTX02 line of 1/8-scale slick tires come mounted on attractive black spoked wheels made for 1/8-scale buggies and GT on-road cars. They are available in S1 (Xxsoft) to S7 (medium hard) compounds; GRP even offers a rain slick made out of an extra-soft compound. The tires come vented in a very interesting way, with four holes around the diameter of the tire, each going from the tire through to and out of the rim. Packaged in a reusable bag, bright orange stickers tell you what compound they are so there’s no guessing or having to mark them yourself.
Bolting them onto my 1/8-scale buggy for testing was easy to do; the rims slid right onto the hex adapter without any binding. I started out with the S3 (soft) compound tires on the buggy and headed to a large, freshly paved parking lot along with the other compounds to try them out. The S3 compound felt right at home on the asphalt, and after a few minutes of driving, the slicks were properly worn in and traction improved slightly. I drove the buggy around for a few tanks and included high-speed turns, speed runs, and so on to give the tires a little taste of everything. After shutting down my buggy I inspected the tires; they didn’t show any major signs of wear, and were still securely glued to the wheels.
Next, I replaced the S3 compound tires with the S1, drove around slowly for a little while to break them in, and then dropped the hammer; traction was slightly better in all areas. After a tank of fuel I made another tire compound change, this time to the S7 (medium hard) compound. After a break-in run I found the tires to have a little bit of a give to them, which allowed me to get some drifting action in; drifting with anything never gets old. Just as with the S3, both the S1 and S7 did their thing and came back unharmed.
Overall, GRP makes great tires; the GTX02 tires are well made and perform nicely. They are a good choice for those who are heading to a
local parking lot or getting ready for a day of onroad racing. While I didn’t notice a big difference in performance in the parking lot, I’m willing to bet that the slight difference in compounds on a prepped track will really allow racers to get their cars dialed in, which tells me GPR means business when it comes to racing. If you’re picking up a set of tires for some parking lot bashing, I recommend the firmer S7 compound; it still provides good traction, and it’s going to last a little longer for you.—kevin Hetmanski

The tires install with no problem. They are slightly smaller than a 1/8-scale off-road tire, so a gearing change will have to be made if you’re putting the tires on a buggy like this.
Yep, that is light you’re seeing through the tire’s vent hole. Four in total vent the tires.
A large and bright orange label lets you know what compound tire you’re about to mount up.
