Is anyone running on 215/40 R17 tires? I'm thinking about getting this size of tire to put on my S-Lites.

 

Using stock 17x7 wheels and stock suspension-

Choices for tires are stock 205/45-17 or more commonly 215/45-17

215/40-17 will also fit the S-lytes but will increase wheel gap and will increase sidewall stiffness and road roughness.

Handling would be better but ride quality and comfort for street use would be less good. If you have poor roads then 215/40-17 is not a good choice.

 

I too will be purchasing new tires soon and I'm going through all the different posts to try to decide what to get in a non-RF. If the only difference in tires is the 215 is just wider why would the ride quality be less than a 205?

Thanks

 

because stock is 205/45, meaning sidewall is 45% of 205mm which comes out to 92.25mm sidewall

215/40 comes out to an 86mm sidewall. so you'll be running on less sidewall than the stock tire size

 

I think he meant 40 series as opposed to 45- typo maybe??

 

Yeah, I believe you meant 215/40-17! I just dumped my 215/35-18's as couldn't handle the stiffness. Every little bump in the road was like I was running a Fred Flintstone wheel! Sheeze, the ride was so rough, that I finally broke down and went with 215/45-17's and I don't notice much difference in the handling, but the ride is a ton smoother on our rough roads.

I also have H&R Springs and an Alta swaybar. There's not too much clearance however, but so far, I haven't noticed any rubbing.

 

Well, I went with the 215 40 R17 on my s-lites and they look and feel awesome. alot smoother and alot more quite than the Goodyear RSA 205/45R17 that I had on before.

 

Enjoy.

Handling is better, turn in response on cornering is quicker.

But road hazzards are greater if you hit a pothole or bump.

Just be careful and if anyone else drives they need to be aware of the danger to damage the tire or rim.
