Can someone loving explain tires to me please. I have an ND with Bridgestone protenza s-01 tires that came with the club trim. I will have to replace them soon, they are ~190$ a tire. However, continental extreme contact sports are ~110$ a tire, but as far as I can tell perform just as well.

What gives?

How many miles did you get out of the stock tires?

OEM tires are always like that. My personal belief is that they’re priced like that to sucker the people who don’t know better and want the same tires as before.

If you’re looking at the DW Contis, why not the PSS or PS4?

I live in Texas so I figure paying ~25 extra a tire for all season isn't super necessary

E: you said pws not DWS woops. I didn't see any pws or PSS for my tire size but I could've missed them

This is usually an unpopular opinion amongst car people, but...

Just put on whatever the most reasonably priced rubber is. Avoid the dirt cheap 'budget' brands and don't get suckered into buying stupidly expensive 'premium' tyres. It's not a 2 ton Rolls or a track-focused Ferrari.

I put on some £90-a-rim tyres and they're great. hosed if I know what brand they are, but it's a sub-ton car. The thing should stop on a dime based on the laws of physics alone.

I got Coopers for the MS6 and after rebates they came to $244/$61per shipped. Heading to Costco this week to get them installed which will run me another $40 but I have a dude who wants my old tires and is giving me $50 for them so in the end I'll be at like $59 per corner. They have pretty excellent consumer ratings to boot. If I needed tires for the Miata I'd probably go the same route.

I spent near £200 a rim on a ton and a half BMW 6er with a 4.5l V8 and 19" rims nearly twice as wide as a miata.

Fair enough if you want sticky track rubber but for street duties, just put some cheap poo poo on. The car is grippy enough as it is.

I don't know what the formula is off hand for ES cars, but I think that you should look into the Racing Beat hallow front sway bar (~$200ish) and whatever sticky TW200 tires you want and dial the alignment in. The much bigger FSB should make the car be pushy (which is faster).

Do autocross to learn what it feels like when the car is starting to get loose so you learn having "fast hands". The track is all about slow hands, but having some autocross background can bail you out. The ideal situation though is to go rent a skidpad with a few friends for half the day and drive around in circles until you puke.

I can usually correct myself quickly enough if I start to step out, I'm just afraid to push it as hard as possible 'cause I don't really know how to maintain a slide if I'm well and truly going sideways. Everyone talks about how compliant miatas are when they get loose but I don't want to be that guy trying to drift it around every corner lol

At those differences, human reaction times, the amount of attention being paid to driving and situation specifics are way bigger factors than the rubber.

Do you have anywhere near you with a skidpan? Aside from being tremendous fun, they're great for practicing handling dynamics and learning to control oversteer.

I'm not sure what point you're trying to make. Here's the same chart for some grand touring all seasons (left) and some less aggressive summers (right) that I randomly looked at (didn't try to cherry pick for better numbers).



Summer tires are still better for this...?

The point was supposed to be that there can be noticeable differences in performance even among good tires, let alone something random from the junkyard. I don't have tests of junkyard tires obviously but hopefully you can kind of extrapolate from there. Of course it doesn't matter if the attitude is "just don't get into accidents".

the point is that if you're relying on 100ms' worth of reaction time distance wise to make or break (or brake?) it on the road, you're not paying attention and having the stickiest tires wouldn't save you

Uh the difference between ~180ft and ~110ft stopping distance 50-0 on wet pavement is loving significant.

Even ~90ft vs ~75f is a pretty big gap, that's like two car lengths. There are more reasons that you may need to suddenly stop than chronic tailgating.

It is. Unfortunately posting charts in isolation that show just a handful of tyre brands and models without any other specifics is dumb as poo poo when it comes to choosing the right tyre for your particular car.

Kinda like mindlessly dropping £150 a corner because "price = quality."

50 mph is 73 ft/sec, and to convert units again, 7.3 ft per 100 milliseconds

are there situations where you couldn't possibly foresee a drastic change in conditions that you can recognize and react to within 200ms? no cheating with hovering your foot over the brake, perfect threshold braking, too.

I think I've figured out why the rubber bits pulled out of the endlinks on the bars. I replaced all 4 endlinks and all 4 swaybar bushings. What I didn't do, is have the weight of the car on both sides at the same time, nor did I make sure the bar was centered. I've also discovered that the front endlinks go on the inside of the sway bar. I'll try to press the rubbers back into the endlinks at work and chalk this up as a learning experience. I'm also going to ditch these ebay springs and use the ones that came on the car. I found older pics and it sits level with those and not all raked. Just like when I was first learning how to build RC cars, I made a few mistakes out of ignorance.

I look at it the opposite way: is there any situation where I wouldn't like to have another 200ms to avoid a crash?

It's a 900 dollar daily driver. I know people race them and I love seeing photos of race builds, I even have a VVT turbo motor that I never put in because the fuel economy will get worse. Spending almost half the price on a daily driver on tires doesn't make sense for me. I had a Lotus Esprit I dumped money into but then I noticed it wasn't really bringing me fun, I like owning cheap common cars I can repair from Rockauto and junkyards. The tires they replaced were hilariously bad, I accidentally burned out an entire intersection in front of a police officer and it scared me so much that I found the new to me tires from a Ford Focus in a junkyard. The old ones weren't even at the wear bars or age cracking, just getting too old. They're 5 profile more than the stock tires, but don't rub and basically feel fine, I can feel they're heavier, but for the price the extra weight is easy to ignore.

This is the same car I JB welded a soda can onto the transmission to stop up a leak. It's not supposed to be nice, just functional.

Who gives a poo poo about reaction time? Yes reacting faster is obviously better but the question is how long does your car keep going AFTER reacting. I had a kid jump out in front of my car and came to a stop pretty much with my bumper touching his leg. A meter more stopping distance might have meant a dead kid.
I'm not arguing that you need super expensive premium tires, but junkyard tires? Jesus, those four tiny patches of rubber are the only thing keeping you and other people from possibly dying.
Are there no tire tests being done in the US? Look up some tests, figure out which tires best fit your budget and grip desire and buy those. Its not that hard.
Also, don't do that "Well i always bought Goodyear tires, they make good tires!" bullshit. They might make great tires one year and then update them next year and totally gently caress them up.

Fair enough. I wasn't going for the whole "You might kill a whole group of school children if you don't buy new tires every year!" angle.

The greater point is that tires should not be bought based simply on price. There are some really good cheap tires, and also some really terrible ones. Conversely, expensive tires are not necessarily better.

Your tires are all that is keeping your car on the road. They're worth spending money on for better performance. Get the best ones you can afford, rather than the cheapest available.

Appreciate the tip. It looks like they push their own end links and mounting flange with it (upselling- the curse of our age). I've got a dinky little Harbor Freight wire welder, but I know enough about my welding that I'd rather pay someone to do it :)

Looks like (reading the SCCA rule book) you can mess with one sway bar, but not both. So that'd keep it in Street.

I just don't know why they sell the flanges as 2 ears you have to fit and weld. Add a bottom plate, make the whole loving thing one integral piece that anyone can weld, and you don't have to worry about aligning it and fitting as you tack it. (Maybe it'd mess with the geometry?)
