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.
;e 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. ;ey are available in S1 (XXsoft) to S7
(medium hard) compounds; GRP even o;ers a
rain slick made out of an extra-soft compound.
;e 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
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. ;e 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. ;ey are
a good choice for those who are heading to a

local parking lot or getting ready for a day of on-road racing. While I didn’t notice a big di;erence
in performance in the parking lot, I’m willing to
bet that the slight di;erence 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

Yep, that is light you’re seeing through the tire’s vent
hole. Four in total vent the tires.
;e tires install with no problem. ;ey are slightly smaller than a
1/8-scale o ;-road tire, so a gearing change will have to be made if you’re
putting the tires on a buggy like this.
