Even my Cayman had understeer, and a lot more than the Boxster, and changing the front tires from 235 to 245 made a HUGE difference.

Suggestion · Original poster

On offramps where it is easy to test the car at its limits (at least for right hand turns), it showed, as you already know, understeer, a little throttle modulation allows one to transition to neutralish.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

20 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 1 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I'm not sure where to find the date code (when these were made) on this tire.. Can someone please educate me? It seems to me that the code as I read it is unlikely to be true (17 years old) so maybe I'm not reading it correctly

POST 2 / ORIGINAL POSTEROriginal post

Also, I have not been able to identify exactly which pilot sport this is... 205/50/ Z r17 Does anyone have a link that shows which exact Michelin tire model this tread pattern is?

POST 3Original post

46th week of 2005. That is super old and needs to be replaced

POST 4 / ORIGINAL POSTEROriginal post

Quotes source post: 648021

I thought the date code said 2005, but I thought that couldn't be right since the sidewalls don't look old. Thank you for the info. I'll schedule to get new tires this week. I just bought 2 new 255 40 17 Firestone Indy 500s for the rears so I will buy 205/50/17s for the front to match

POST 5Original post

If I were you I would get 225/45r17 for the front to get rid of the understeer that these cars have. I lot of people on here go with a wider tire at the front for that reason.

POST 7Original post

Quotes source post: 648046

are you implying that you are able to generate throttle oversteer in a stock boxster or that you let off the throttle when the car starts to push

POST 8 / ORIGINAL POSTEROriginal post

Quotes source post: 648061

My statement was, and I quote " I tend to use the right pedal to reduce the understeer " The fastest way around a corner is usually the smoothest, so sometimes a little patience with the throttle is the fastest way. Sometimes you have to lift a little to maximize overall speed through the corners. Finesse is faster than wrestling with understeer. A little trail braking can help. So my answer to your question is: no, not completely, but can come close to throttle induced neutrality. On offramps where it is easy to test the car at its limits (at least for right hand turns), it showed, as you already know, understeer, a little throttle modulation allows one to transition to neutralish. The modest 200 hp is plenty under these conditions. The trick is to use most or all of what is available power and grip most or all of the time. The stock car I find handles close to neutral, it appears the engineers intentionally kept it in the safer understeer range to save idiot drivers from themselves. I think the engineers did an excellent job designing this car. If one wants, they can change the set up to be more neutral or even some oversteer I suppose...

POST 9 / ORIGINAL POSTEROriginal post

I found this tutorial helpful: https://driver61.com/uni/understeer/

POST 10Original post

I have significant track experience, so yes, I'm familiar with understeer. I was more so questioning anyone who thinks a stock boxster will induce throttle oversteer on a dry road with a decent set of tires.

POST 11 / ORIGINAL POSTEROriginal post

Quotes source post: 648087

I see. :-) I think my post set off your B.S. proximity alarm haha So do you agree that my follow-up statement was factually accurate?

POST 12Original post

Quotes source post: 648062

I get what your saying, and I agree, but wouldn`t it be nice not to worry about the car understeering in the first place? I prefer a car that oversteers than a car that understeers. I`m no engineer or expert, and I`m sure Porsche engineers designed the car to understeer for a reason, but you would be surprised how much of a difference a 225 tire makes at the front vs a 205 on these cars. I can take turns a lot faster with a 225 vs a 205 without trail braking. I like fast in fast out Even my Cayman had understeer, and a lot more than the Boxster, and changing the front tires from 235 to 245 made a HUGE difference.

POST 13 / ORIGINAL POSTEROriginal post

Quotes source post: 648098

Hmmm, I'm surprised it makes a big difference. Good thing for me my local Firestone was busy until next week. I'll switch it to a 225 50 17 instead

POST 14Original post

Quotes source post: 648099

Go with 225/45r17 if you have 255/40r17 at the rear. It will be a better match.

POST 15 / ORIGINAL POSTEROriginal post

Quotes source post: 648100

I know it may sound crazy, but I prefer a little more shock absorption by the taller sidewall. 112 mm vs 101mm sidewall It raises the very important WAF (wife acceptance factor)

POST 16Original post

Quotes source post: 648101

I understand , but you are going to be almost an inch higher at the front vs the rear.

POST 17 / ORIGINAL POSTEROriginal post

Quotes source post: 648102

* update Somehow my calcs are wrong, Firestone is reporting the 255s at 25" and the 225 at 25.9" Sooo yeah, almost 1 inch difference.

Thank you for that, I was busy doing it on my calculator. Yeah, the 45 series is better. It would probably look weird .9" higher.
