Tire question

[XTCshri2222]

what is the best 245 45 16 tire avail for autox and one that can last about 7,000miles some of which would be 11 events

[glitched]

There wont be a single "best" tire.

First you need to decide if you mean street tire or not. Street tire classes limit treadwear rating to 140.

after that, different cars/courses/temperatures will affect which tire will best fit your needs.

The top players in the street tire category are:Bridgestone RE-01RFalken AzenisYokohoma Advan Neova

But i dont believe any of those come in 245 widths. 225 for bridgstone and falken

what are is your rim size anyway?

[XTCshri2222]

my rim size is 16x8 i'm currently running 225s but I'm gonna be in SM class running some M3s in my region, I'm not expecting to beet them, but i still wanna place high so i can have a chance winning the regional points for sm class. And from what i know SM class dosnt have a tire regulation, so i dont mind if there not a street tire, i just need to be able to get 7k miles out of them for when i drive to the event and drive to a few shows and do one time attack on them. Unfortunatly I dont have alot of cash for the season and i want to attend alot of events to finnaly enjoy my car after sitting on the side lines for 4yrs.

[XTCshri2222]

I see your points champ, i enter this yr as a novice, but i'm 26 and have driven a few autox's before just for fun 6yrs ago. Got any recomendations for me to setup my 240?

Why would you not go with a street tire if your on a budget and need to drive to and from the events on the tires you race on?

You need to go with the Bridgestone RE-01R-225 will be better on an 8in rim. Strait and stiff sidewall = better response-You'll get the mileage you want out of them.-budget friendly-and of course amazing grip from a street tire.

Check to see if they have a street tire index for SM. I ran in SM on street tire index when at some events. Specifically, it was a Rear wheel drive street tire class on index.

Two years ago, I was 24 when I entered my first full season as pretty much a novice, but I was out there every weekend, attending events for multiple clubs, track days and all. i was able to squeek out the points championship there at the end of the season, and because of the dedication to improving myself, and pulling of the points championship i also won rookie of the year that year.

I've got lots of tips to share, but There's lots of tips and recommendations out there. look around and come back when your ready for more

[evildky]

the reo1R's will definitely last the 7k miles, hoosiers or v710's would offer a lot more grip but tire life is iffy, also kinda depends on how much camber you run, the victoracer v700 might make a good middleground

[crackler]

First off the re-01r have been replaced by the re-11r, secondly, the hoosiers and v710's will last you about 50 miles, if you are lucky.

There are several street tires to choose from in or near that size. If you don't have a dedicated set of rims, DO NOT buy R-comps. They may be D.O.T. rated, but they are not meant to be driven on the street. I don't think the victo racer has been made for the last couple years.

All have new UHP tires available, if you are running SM and don't have a set of wheels for R-comps, check o see if your region offers a street tire class. That way you can compete with other street tire clad cars based on pax (BTW; SM PAX SUCKS!) instead of getting killed by guys running A6's

Check SCCA forums - street touring section for the latest opinions on the new tires that are either just out or soon to be out.

Just go out and have fun, and try to improve your driving the first couple years. And hit as many "schools" as you can afford. That is the est money spent imho.

[evildky]

forgot about the new bridgestones, but you severly underestimate the tred life of the V710, when you are driving ont he street they wear a bit slower, I've driven to a fron events on mine, some guys drive them to and from every event, some are putting 50 miles round trip every time they do this

[crackler]

You can't seriously be suggesting he get a set of V710's for daily use.I know guys who have drove to and from events on v710's. But there is NO WAY I would recommend some one using them as a primary set of tires. Track / AutoX only. Or maybe if you live close enough, to and from events. What if it rains? Do you just stay home that day?

And yes 50 miles is probably a little low, especially for the non A6 tires, But there is NO WAY they are going to last 7000 miles, especially when you factor in a dozen autox's and a TT.

Hell I probably have less than 3 thousand street miles on my 615's and a about 2 seasons worth of autox's and the inside shoulder is down to the ware bar. and they are a 200 treadware, not a 60.

[sr20goofus]

whatever wheels you plan to use for auto-x, make those set for track/auto-x use only and get some crap wheels to cruise around on daily. Stuff those other wheels into the back of your car for the events and change them there, optimize life of the tire especially if you are on a budget. Dont make silly comprimises because someone else's friends friend did it one time and it was fine. If you are on a budget, evaluate your budget and then see what makes most sense. R-comps prolly arnt your best choice, but if you are set on getting some, then by all means do it and let us know how fast they wore down.

Dont forget auto-x r-comps and roadrace r-comps are different, auto-x tires dont need to be warmed up, and roadrace tires do. If you use roadrace tires for auto-x then you wont get the full potential of the tire because they will not be warm by the end of a run, waste of money spent basically. If you use auto-x tires for roadracing then they will be completely worn to the cords in 2 sessions maybe, too soft for those high grip high heat situations. Street tires are the best for doing both, make your decision carefully.

Thanks for the imput, i've been concidering after all the advice some dunlop direzza star spec, or the bridgestones in 225 50 16 . It seems to have good reviews and seems like a good sticky tire.

Cracker, i've been tring to understand pax, but im not 100% with it. In SM class is there a seperat "pax" for street tire vs R compound ?

[crackler]

Same pax regardless of tires. A "Street Tire" class is a group for people to run in that CAN run R-Comps but don't have / can't afford / don't want to hassle with R-Comps. Then each cars / drivers time is multiplied by its PAX time to determine a winner (Who ever has the lowest PAX time).

PAX is a multiplier given to each class. One class (I forget [A Mod???} is 1.0) and (I think) every thing else goes *down* from there. There is a guy out of (I forget from where now) that comes up with the multipliers every year. And adjust any given class according to how they did against the other classes.

An example using totally made up numbers. . .

class "A" would have a pax of .856While class "B" will have a pax of .849and so on.

Class "A" driver runs a 49.412 multiplied by .856 gives him a PAX time of 42.2966Class "B" driver Runs a 49.658 multiplied by .849 gives him a PAX time of 42.1496

So even though Driver "A" has a faster raw time, Driver "B" has a faster PAX time. So if they both where in a street tire class together, driver B would have won. Hence why I said SM PAX sucks.

There is even software out there that you can plug any number of drivers in any number of class's to keep track of their pax times, and tells you what raw time you need to run to beat their pax time.

Clear as mud???

Here is a more detailed explanation, with some slightly old pax values. http://mokanmotorsports.com/fo...t=507

[XTCshri2222]

It's clear now, thanks alot for posting. I'm gonna be in SM, I built the car for Redline Time Attack street class rules, problem this season, there is only one event in any reasonable distance. So I decided to change up a few things and go autox. It took a long time to get my car to where it is, taking parts off to satisfy a new class im not gonna do, i'll just have to drive better. And not get owned by the 2 M3's who won SM class points in my region haha. My plan is to just make more events and earn more points, i doubt i can keep up with the M3's tech with 20yr old chassie.

Just go out and have fun. Don't worry too much about how you stack up against guys with more experience / more developed cars / proper tires. Your first couple years are a learning curve more than anything.

The car looks really good BTW. And I don't blame you for not wanting to detune it.
