Anyone carry wheels/tire to track in or on their vette?
 
Anybody carry their slicks to the track without a truck? My local track, PBIR, is only about 15 miles away. I can carry 3 easily - 1 in the passenger seat, 2 in back. I can carry all 4 with the trunk left open, maybe I can put a cover over it for weather. Was also thinking of making a single wheel/tire carrier and attaching it to the rear deck. I have a fiberglass spare tire carrier from my C3, could possibly mount it.
Thoughts?

Here are pics of 4 tires in the car for reference:

What about building a light duty receiver hitch that you allows you to put in a slide in cargo rack/tray to carry at least 2 of the larger tires outside the vehicle? You'd be carrying less than 130 lbs (two tires and slide in tray) so I don't think that the strength aspect is going to be an issue. I saw what this guy did with a simple receiver hitch from Walmart to haul his trailer.....probably could work for what you're doing.


There are a lot of downfalls of driving with your hatch open....at least you're close to the track. But if you take further trips, then I would think the vacuum created would be sucking in a LOT of dust and exhaust fumes into your interior.

for only 15 miles, what is the issue with just driving to the track on the slicks?
(forgive me i run "treaded" 100-200TW tires and not super familiar with slicks yet.)

67Ranger 03-15-2019 02:56 PM

I dont think you'd have an issue driving on them to the track if its only 15 miles. I'd definitely do that on slicks or R comps before putting them in the car.

Iím on Hoosier R7s now. Theyíre good on the street, great when itís warm out, which it is here in south Florida. But they wear a lot on the street and Iím potentially adding heat cycles. Iím switching to Pirelliís by this summer. Theyíll heat cycle on the street, and are very fragile. Itís a pretty easy drive to the track, but why wear out the slicks? I can change them in less than 45 minutes. Have to change them anyways, so why not do it at the track?
Iíll be going to Sebring this fall. Itís about 80 miles. Definitely want a good solution by then.

I drive up to 8hrs on my Nitto NT01's to get to the tracks in the rain. Wouldn't do that on slicks, but only 15mi on a fair weather day? Of course I would.

Thanks for the suggestion. Going to look further at carrying on the back hatch. It can certainly support 1 wheel and tire, under 50 lbs for a front.

I used to carry my track tires/wheels and tools in a small Harbor Freight trailer. The hitch was custom designed to fit my C6Z without cutting holes or altering anything, just using factory mount points. I gave up changing tires at the track so use the hitch as a rear tow point.

UstaB-GS549 03-17-2019 09:41 PM

Other than driving in the rain I can't see why you would want to transport tires 15 miles. It's not like you will get them up to temperature to heat cycle them.

With my C5 I could fit fronts on passenger seat and mount slicks on rear the night before leaving. If it rains you are limited to about 60 MPH with street fronts and slicks on back.I did this for many years.

I wouldn't want the flimsy C7 hatch bouncing around... just drive to the track on them.

z06801 03-18-2019 05:05 PM

^I agree if they're just r comps.
Are you running Sport Cups? If so I would just drive them there on the car.

Mick14 03-18-2019 05:43 PM

If it is only 15 miles just drive. I would even do that on slicks if weather was ok. You will not get them hot enough to heat cycle them.

fatsport 03-18-2019 08:58 PM

Iím on R7s now, going to Pirelliís in May. The Cup2s are for the street and longer distance tracks. Running Charlotte and/or Road Atlanta this summer, visiting good friends in Greenville.

Really enjoying your build thread :thumbs:
How flimsy is the hatch? Are you going to run an APR wing? If so it can handle 500 lbs of downforce, why not a 60lb wheel/tire/carrier setup.

I'm going with a chassis mount wing. Just push down on your hatch with it closed and you can see it flex relative to the quarters a large amount. If you close it to the first click (I don't have the power pull down) and then try to push it closed over the latch you can see it flex (my C5s never did that). There are some stories of 2014/2015 owners cracking the paint in the hatches closing them before they brought back the power pull down. There's a reason GM went to the trouble of a chassis mount wing on the ZR1... if they cold have done it on the hatch they would have. Interestingly the ACR Viper which makes massive downforce does have a hatch mounted wing. However, I have read that the hatch is carbon fiber and was reinforced for the wing.

If you look at where the hatch hinges bolt to the inner shell of the hatch you'll see that area has to support the load of the whole hatch. I just wouldn't want it bouncing up and down repeatedly driving around, but that's me.

If I had a track that close I'd drive there on Hoosiers, or you can get a hitch and a little tire trailer.

Great info, thanks. Iíve seen chassis and deck lid spoilers on C7s at Sebring. Didnít ask about cracking or durability issues.
Are you going to fab your chassis mount yourself? I think I have a pic of a home fabricated one I saw, Iíll post it.
Iím doing PBIR this Saturday, will drive on R7s for now.

dparm 03-21-2019 07:10 PM

Honestly, I would be very worried about the hatch bouncing against the tires and breaking the rear glass.

Find a way to drive there on the tires, have a friend bring them to you in another vehicle, or ship them to yourself if it's farther away.

One of our customers fabricated a receiver to the frame behind the license plate and used one of those carriers you see in the rear hitch of SUV's. Quite impressive actually, the receiver is hidden by the license plate when he isn't using it.

fatsport 03-22-2019 10:50 AM

A friend snapped this pic at Sebring a couple weeks ago Home fabbed wing and carrier on a C7Z. Was running 30/65/18 & 30/68/18 Michelinís on Signature wheels.https://cimg4.ibsrv.net/gimg/www.cor...c5e1b6afc.jpeg
