Has anyone changed the stock 17" tires. I am looking to put 215/40/17" tires on mine.

 

I have been thinking about changing to 215/45/17 myself. Maybe someone will share some insight. I have changed the tire sets several times but never to a 215.

 

Very common swap. I run it with a slight lowering from NM springs with Konis. No rubs, no issues. A little more comfortable a ride than with 205's I think.

 

I have never swapped my summer 17"s with anything else but 205/45 but I will add my .02 cents from my expierence recently changing my winter tires. I have a set of 15" rims and bought some NITTO SN2 off tire buyer for a song (270 for 4), and wanted them installed at a local dealer, a quote of 30 per tire installed and balance by my local premium tire shop had me looking elsewhere though. I thought I could save some cash and just have Tires Plus change them out... they wanted 180, just to mount and balance a set of tires. Mouth open, I told the service attendant to sell that ketchup pop-sickle to another schmuck, and left. Across the street, at an NTB store, got them all installed and balanced for 90 flat.

BTW, I didn't think that a tire shop would install oversize tires on consumer vehicles, is that still the case or running a 215 on a 205 rim too negligible to make mounting those tires unsafe?

 

At Discount they are an optional size for the application, so they should install them. Dealer will not. I've had no problems getting 215s swapped or installed on 2 separate cars at Discount. If you live in the sticks, Tire Rack may be a great alternative to get what you want.

 

I am going to lower profile so ride will be rougher but handling better. Both my dealer and Discount Tire says 215/40/17 will be fine and Discount will install them.


Thanks for your replies. I will let you know how they turn out. I am probably going with the Nitto Neo Gen.

 

Don't forget to post photos too!

Just a suggestion, for improved handling without sacrificing comfort, why not run a grippier tire instead of a lower profile? I'm hoping to ditch my 17" runcraps for a set of 16" with hankook R-S3s.

 

I ditched factory runflats after 500 miles,they were loud and harsh. Went with Hankook S1 Noble 2 (UHP all season)215/45-17. NO mounting or clearence issues at all. I will run these till Thanksgiving then mount my Tirerack winter pkg.(195/55-16 Blizzak WS80 on 100$ alloys)No 16 inch steelies available for our F-56. Lose the runflats,you will be happy!!

 

Thanks for the info. I've got only a little over 200 miles on mine so we are on the same page. I'll let you know how the lower profile works out.

 

Also I went with Nitto Neo Gen. $490 installed including tax. The smaller diameter will throw off the speedometer but only by 2%.

 

I had the 215/40/17 Nitto Neo Gen tires put on today. So far much better than standard run flats.

 

Good deal,you will never look back!! Play with your tire pressure,start high adjust down.You will find the best ride.

 

Going to lower profile and wider tire turned out great. 215/40/17 is the tire for tho car.

 

does it change your speedo accuracy?

It does affect the speedometer but only by 2% which is not insignificant but acceptable to me. Check out the site below. Go to the tire size comparison. Put in current tire size and optional tire size. It will tell you everything.

so 215/40 is better than 225/40? It show both sizes be equivalent in that calculator you shared.

225 will fit the 7" rim but are pushing the limit. Using a tire that is too wide for the rim (even marginally) will negatively affect handling. Also 225/40/17 is a very difficult and expensive tire size to find.

 

thank you. I am very interested in trying the 215/40 size!

I find only two tires on Discount Tire's site in 215/40/17. There are tons in the 214/45/17 size. Opinions on that size?

 

They had many choices when I stopped by the store. More then on website. Tire Rack has 10 or so.

 

I attached a couple of pictures with the new tires (hopefully).

 

I'm looking to purchase a set of winter wheels and tires but I'm worried about the TPMS. How did you deal with finding the right TPMS that will work with the car?

 

Talk to someone who "knows their stuff". My suggestion would be Eric (Ext. 4314) at Tire Rack.

I just installed my winter setup from the Tire Rack today, and all's working just as it should (including TPMS).
