Sub 2 minute driver/co-driver tire changes?

Over the years I've been hearing of tires changes during a race "on course" being done in under 2 minutes by usually just the co driver. Is this the acceptable standard I need to include in my resume for a right seat position? If so please include helicopter, in car or other videos that you may have both in practice and real time so I can compare my times.
Disclaimer: This is mainly for my viewing enjoyment and probably others as well and I'm not looking for seat time either unless my arm gets bent in an uncomfortable position. Please refrain from posting about "his belts weren't even on all the way when they took off" because that's been covered before. I just want to see it for myself as the finish line interviews always have some great times announced to the world.
one of my co-driver friends has been doing serious fitness training for the last few years so he doesn't get winded during tire changes and pushing. granted it's only Class 11 and the tires are lighter, but they end up do a lot of pushing/recovery work, while the driver stays in the car. I can see people doing interval/weight training just to minimize the tire change time. BTW, we got first at the last B1K and all that fitness training certainly had an effect in their section, because they got stuck several times and had flats.

We had better luck when I stayed in the car with my foot smashed on the brake to keep it from rolling. We tried the scissor jacks but they didn’t work. We used a high lift type of jack I think was out of a Cadillac that was light, tall and strong. Just put a bigger plate on it. We had good jacking locations on all 4 corners of the car. We could do sub 3 minutes changes but nowhere near 1:05 or even 2 minutes. . One tire change took us 25 minutes because the tire chords had made a birds next in the hub. What a mess that was.
Sub 3 minutes without on board jacks is a nice compromise and probably still above average by far after hearing from our fellow racers in the 10+ range.

What do most drivers/co-drivers prefer when you pull into a checkpoint to change a flat? Would you rather be left alone? Or want our help?
Its a toss up. If you cant accept help per the race org and someone with one of those new camera phones happens to be taking pictures it leads to drama here. Other times if I'm in my zone I'd rather do it myself so I don't mow someone down that's in the way. Don't think it saves much time if any. Now if the terrain is sketchy and the jack doesn't work properly than by all means give us a hand for safety reasons etc

One cool feature of our new brake shut off valves is we can use them as emergency brakes. Just push the brake pedal and cre pressure then close the valve for the front. Works great.

we figured this out for crew change when we are changing rear tires. So the front wound stay out and we didn’t have to have someone chock the fronts during the pits.

we are going to start practicing both driver and co getting out to change the tire.

Something not mentioned on these fast tire changes is that the driver is moving before the codriver is buckled back in. It’s only a few seconds for a good codriver but it’s a scary few seconds.
I think the reason codriver only changes are just as fast or faster is because there is no waiting for the driver to get buckled in before taking off.

Some drivers will not leave until I'm belted. Again this was meant to see how its done (just tire change) so fast (want proof) and in no means to disregard safety to get quickest time.

Are guys using electric or air impacts on these changes?

I was at the 2007 BITD Vegas to Reno (MM17 near the start), the TTs came then the limited classes. The Camburg truck pulled over. I heard electric impacts being used

2 years ago at KOH i seen Andy's co driver do it easily under 40 seconds, 35 is what i was thinking it was. No re rack, but the ratchet strap tightening took him a bit of the time, tire left at course worker. I can tell you it was damn impressive to see in person. Amazing.

Thats a great question! I wish more people would have thrown an answer at you. for me, I would welcome the help, but often times the checkpoint worker isnt a racer such as yourself. so in that case that may just get in the way. I think the racers that are working the race will jump in and help anyone. maybe the workers that arent "racers" would probably ask, "can I help you?" At that point I may say no as they probably are not racers lol Sorry for going in a circle....

Someone else mentioned getting in trouble for "outside assistance." I do not believe a course worker helping you is "outside assistance" I know with SNORE we encourage our course workers to help racers get back on the track. "outside assistance" is more about your pit crew coming and helping you outside of a pit area.

i got lucky in Barstow , got a flat right at a group of fans, luck of the draw, changed flat, they helped load flat& that allowed co rider to get in a little quicker, 50 yards earlier or later and we be on our own,i think All out side assistance is fine as long as its Not fuel or parts

If it’s a top team in any class i’ll stay out of the way unless they ask for help. But for the weekend warriors most tend to welcome the help. Never have encountered a racer get mad for trying to help thankfully.

It’s not against the rules to ask course workers for help. Which most racers tend to not know. That’s why we’re out there is to help you the racer. I can’t even count the quarts of oil i’ve given out, rolls of tape, ratchet straps, tie wire, zip ties, etc...

Thank You!!,the oil part paid off for me at Parker, came in to checkers pit for broken control arm, and they pointed out oil leak( rear main, too much crank case psi, its a jeep 4.0 quirk), they topped off fixed arm and we finished

I have been go over our in car cams from Vegas to Reno and had a question about how long people will push on a flat.

The boys had a front flat and went about 4 miles and then realized the pit was another 8 miles so they pulled over to change it. The change was a disaster as it was on sand and the front is very hard to change in the sand. Plus they were totally gassed, watching the video was painful LOL. Total time on side was 21 minutes for the change.

Anyway my question is would you try and make it 9 miles to the next pit? I guess whats the mileage thats too far? I am just wondering if they should have kept pushing with the front flat for another 9 miles. Or would they most likely do more damage? Obviously our stop was a mess so hopefully that wont happen again.


Would like to hear how far others have made it on a flat.

9 is too far, in 1700, i would drive until i got to a Very friendly tire change location on nice flat hard out of the traffic ground, if you wad a tire carcass around the upright/ rear axle , then your fffudged, now, if your in the last nine miles of race.....burn that motha' Down!!

Co-dawg is also unbelted, window net down and halfway out by the time the truck stops moving.
