Ogren-Engineering Posted March 14, 2017 Report Share Posted March 14, 2017 In the beginning.. Tires lasted two races or more. The latest/fastest, tires wont go 6hrs on a Miata. Maybe 2017 should be a data gathering year with a short list of banned tires at the end. Most of the new issues fail to make the 6hrs IMHO. Thats not what Chump is about.

Technical Advisory Committee Andrew D Johnson Posted March 14, 2017 Technical Advisory Committee Report Share Posted March 14, 2017 While we are at it, tires should be 205 width maximum to save money. Wider tires are not what chump is about. 1 Quote Link to comment Share on other sites More sharing options...
Technical Advisory Committee Andrew D Johnson Posted March 14, 2017 Technical Advisory Committee Report Share Posted March 14, 2017 I would also be OK if it was moved down to 195 width max Also, cars burn way to much fuel. I think we should cap all cars to a maximum of 10 gallons of fuel. 5 Quote Link to comment Share on other sites More sharing options...
Ogren-Engineering Posted March 14, 2017 Author Report Share Posted March 14, 2017 Wider tires can go all day. And come back for more. Our 275 last mutiraces. the 215 wont. 1 Quote Link to comment Share on other sites More sharing options...

In the beginning 4.3.2. After any previous ChumpCar World Series (or other) racing event, teams may replace any worn, broken, ventilated, impaled, defective or bent-beyond-all-recognition parts on their car -- anything -- without affecting the value of the car so long as it's a used or junkyard part and it’s OEM and it's 100% stock. No new parts; no aftermarket crap; no OEM part that's been modified or upgraded in any way… and no swapped parts just because they fit. Everything has to be OEM and 100% stock and wellused to qualify for the no-added-value pass. It would serve all teams to keep their junkyard or CraigsList receipts 2 Quote Link to comment Share on other sites More sharing options...

I hope you are right. if mike's suggestion was taken seriously I would have to build a wide body car, and spend a ton on wheels and fabrication.

drgchapman Posted March 14, 2017 Report Share Posted March 14, 2017 (edited) We usually run a full race weekend and one more day with a set of tires (225x16's). If you are wearing tires that fast something else must be causing the excessive wear. I would look at your alignment and then..........your drivers. It is very easy to drive the tires off a car pretty quickly with "driving style". Pushing into the corners too hard comes to mind and is what I see as an instructor so often. Spinning the inside wheel on exit is a common one as well. Edited March 14, 2017 by drgchapman Quote Link to comment Share on other sites More sharing options...

drgchapman Posted March 14, 2017 Report Share Posted March 14, 2017 (edited) Enginerd, We have run the Falken 615's, BFG Rivals, Dunlop Direzzas, and are trying the Proxis R1R at our next race. All these tires run ~$640 the set. If you are speaking to 200TW tires and are lobbying for 300-400 TW tires, good luck. No one wants to race on those rocks, they also chunk out and fall apart. They are not designed for what we are doing. Edited March 14, 2017 by drgchapman 1 Quote Link to comment Share on other sites More sharing options...

Tried several different tires and they all seem to last a least a race weekend. Our car is also much heavier than a Miata. Quote Link to comment Share on other sites More sharing options...

They are not designed for what we are doing. The Falkens, Rival, and Direzza are three of the most popular tires out there. It is common knowledge that these tires will last a weekend and are legitimately 180-200 TW. The point of the post was to consider a ban on tires which have been introduced which are drastically softer (and therefore more expensive) than normal 180 TW tires. [edit] As Red0 wrote below, there's no good way to implement something like this. The existing system is unbiased and objective... any attempt to regulate this would be based on a subjective assessment of performance and cost. If this is all about cost, would you ban certain tires because they cost more than another brand of similar performance? Would you limit widths / wheel diameters because larger diameters cost more? Would you ban tire shaving? It would be a subjective can of worms so it shouldn't be a rule. Edited March 14, 2017 by enginerd 1 Quote Link to comment Share on other sites More sharing options...

Race Control chisek Posted March 14, 2017 Race Control Report Share Posted March 14, 2017 Our tire rule is 180TW and up. It's not changing, even if the tire manufacturers are cheating their own standards system. 15 Quote Link to comment Share on other sites More sharing options...

It's a direct result of the dumb ass "Grass Roots Motorsports" articles that talk about 1/2 second per lap better tires. Not looking forward to what happens to my Direzza's in the next rev.
