I'm looking for a little insite. My car is at the point where it could use a new set of tires, however, being that I am currently a medical student, I really don't put many miles on the car. In fact, of the 200-250 miles a month I am currently putting on it, 80 are just from driving to my monthly solo2 event. I have been wanting to move from a local street tire class to AS, so my question is would it be possible to just buy some hoosiers and leave them on the car full time. The majority of my non-autocross miles come from quick trips to he grocery store or coffee shop, and I don't drive it in the rain as is.

How would the tires wear in such a situation with a fairly aggressive alignment.... or more to the point, how much extra wear could i expect from the incidental milage compared to the autocross wear and how long would you expect them to last in such a situation.

What pitfalls do I need to consider?

Thanks

 

Especially with autoX compounds, you need to worry about "heat cycles". Some tire compounds can only get hot and then cool again a limited number of times before they loose their grip levels.

 

The race tires would harden prematurely and there would be much higher risk of punctures than with regular street tires. It used to be possible to use Victoracers or ECSTA V700s for evryday use, but with the current state of the art autocross tires? No way.

 

I agree with the other guys. A compromise, if you don't want to get an extra set of wheels and tires, is to use full-tread NT01's or R888's (track tires). They'll wear faster than summer street tires and may not be ideal for wet conditions, but won't heat cycle out as badly as the Hoosiers A6's or Kumho V710's (autoX tires). I'm not sure if they would heat cycle out if you're using them for daily driving though. I know of some guys who use RA1's for their around-town weekend cars.

I use NT01's for both track and autoX, and to drive to and from the events.

 

all depends on HP levels and how you drive the car. my hoosier a6's last 20 sixty second runs before i need a new set.

i have not run them at an event, ( i will this sunday) but i suggest running the r888. smooth on the highway, great in the wet when full tread, overall a great all around tire.

 

The current opinion around Atlanta Region is the Hoosier A6 is good for 50-60 runs. The komho V710 will be good for about 80 runs and you will see cord at 110-120 runs.

I used the Hankook RS2-212 last season.(AP1, 225/50X16 front, 245/45X16 rear) They are about 2 seconds slower than the Hoosiers on a minute course. They are cheap from Edge Racing or Discount Tire Direct.

not nationally competitive life, no way.

 

I will be driving from Ohio to the Dragon on R-comps (Advan A048 medium compound). I also did it last year with no problem. As long as you don't drive in the rain and don't mind a treadwear rating of 20 (ok not really but they don't last long at all).

 

How would the r888 compare to Falken Azenis Rt615? Also, what are the widest tires i can put on without running into deminishing returns... i have heard mention of 245/front and 275/rear. (which are too big by the manufactures rating for AP2 v1 rims)?But even similarly sized tires have different absolute tread widths, so how much wider than the rim can one go to get the most tire on the ground before the tire starts to have issues... in general?

I appreciate all the help.

 

+1 to getting some Toyo or Nitto track tires. I currently use some old Toyo RA1's for autocross (and driving to/from events). They may take an extra run to heat up compared to Hoosiers, but being able to use them on the street without taking much competitive life out of them is great. And unless you have a very talented group of local drivers, they should compete very well.
