best way to approach tire setup for cornering

I have never heard of the weight/insq change in contact patch effecting grip. I have heard of having too big a tire/wheel and having that slow you down but that was just for drag.

From what I've read, tire compound is the biggest thing you can do for more grip. If you can afford lighter/wider/bigger wheels and sticky tires then yeah go for it but if not just the sticky tires will be good too.

Thinking about the weight/insq of contact patch again, couldn't that be adjusted for by changing your spring/dampening rate? Or by adding down force?

I dont think weight has anything to do with handling. The anon above has the right idea, but don't fall into the "pigfat" meme. 4000 lb performance cars handle better than some anon's 2700 lb integra. It's all about suspension setup and tires, so you do have the right idea.

>handle better than the Integra

Unpossible.

Larger wheels = more weight plus worse handling.

Stick with the 16 maybe 17 inch wheels. Wider tires are only going to increase your grip overall, although you can probably experiment with the pressure and get relatively similar results.

FWD or RWD?

No.

Yes. But that can be kind of difficult to do on a normal street car.


I'd say look into what the best performance tires are, then size them as close to appropriate for your car and go with that. You'll probably end up needing new rims anyway.

By that I mean, if the grippiest tire you can find in your size is a 500 treadwear with a 50k mile warranty, you're probably going to want to change rim diameter/width so you can get something with an R compound instead.

Wider tires on a lighter car will drag more, scrub more speed, and take longer to heat up. If you have 800 HP, don't give half a shit about rolling resistance and run endurance races, get the widest tire you can get your hands on.

If you're just looking to have some fun on the way to work, find something with a good compound with good reviews, size it relatively close to your stock tires, slightly bigger is fine, and use that. It'll like as not heat up just fine in regular driving and grip more than you ever actually need.

I'm no expert on this stuff but from what I've seen braking has a lot to do with getting the most out of your tired. The less you brake in the corner itself the more grip I get out of the tires. This all probably really basic to everyone except for me. Just figured I'd give me 2 cents.

God I miss that show.

Fuck, I know buying new rims + tires is probably the better option (so then I can have a set of "all seasons" stock rims to commute on and then a weekend set for autocross/touge), but a set of 225/45/16s ultra high performance tires are pretty cheap. Don't want to buy some and then wear them out commuting though.

Huh, does weight really not have that much to do with handling? What about weight transfer in turns? If your car is heavier won't there be more weight shifting around?

RWD.

My car's not that powerful so going for fuckwide rims could gimp it a bit. I'm looking at tires for my size and it seems that bridgestone potenza re11's are fairly affordable in that category.

Thanks, I'll read through this.

I love threads like these, mainly because i learn about shit i have no clue about.

Wish /o/ was more like this instead of shitposting central.
