Quick question, looking at new all season tires. Between DWS06 and the Michelin AS4. DWS only comes in 315, and the with the AS4, the 315 is noticably cheaper, vs 305 (ironically). I know some people have done 315s on a widebody, but will there be any issues in drivability or how the car behaves with a 315 vs 305 on stock 11 inch wheels?

Don't look at the sidewall number. Look at the section width. Some 305's are as wide or wider than a narrow 315.

My Conti 305’s have only a 1/4” narrower contact patch than 315’s.

Gotcha, looked up stock tires and they show section width of 12.3. AS4 in 305 are also 12.3, and 315 is 12.4 (such a minimal difference). DWS 315 clock the largest at 12.6. thanks guys

I have the DWS in the 315 size with no issues on my Hellcat WB Charger.

I assume you're comparing load ratings as well? Both 106Y XL?

Assuming we are talking about the Michelins, then tire rack shows the 305 as 107y and xl rated, and the 315 at 110y and xl rated


Edit** also checked the dws at 315 and they show as 110y and xl rated

My Conti 305’s have only a 1/4” narrower contact patch than 315’s.

Would that be on the same-width wheels?
Technically, wouldn't the 315's want wheels that were wider?

Bingo!

1/4 is alot

1/4 is alot

6mm less so its a 310 vs 315.

Say what???????????? I'm lost, I didn't do well in English v. Metric! 😁

Its all good my American friend. The 315 is in mm for section width. An inch has 25mm. Quarter of an inch is 6mm. I'll let you fill in the blanks from there.

315 Is the tread width in mm. Divide mm by 25.4 for inches. 1/4”=6.35mm

 

[baabootoo]

Neither make the same size either. Conti is 305/30 and Michelin is 305/35, right?????? That will affect diameter more. Look on Tire Rack for details.

I just ordered the Conti in 315, read in other post's it's no issue.

Thank you, all I wanted to know. This thread got off topic with load ratings and metric vs English. I just wanted to know if 315s were ok on the stock wheels without losing control or abnormal wear or something. section widths weren't that far off from stock, just wanted to make sure I wasn't going over the edge of doable.

Probably going Michelin as4 in 315/35/30, they are 30 dollars cheaper a tire than 305, and fill out the well a little better.

 

[areuriding]

Yeah, you'll be fine and like them as well. It was a toss up for me between Michelin and Conti's, I think both are quality tires. All the pics I've seen with people running the 315's look really nice.

Or .03937 x 6mm = .236”😁
