No fenders and tire sizes
So I have been doing a lot of research on tire sizes that will work with stock fenders. My fenders have been sleeping soundly in the garage for the past 2 yrs with no plan to put them back on. I am not saying I want to go as big as I can since I don't have fenders but what is a smart way to approach this? I am scared of getting into trouble with the nanny too. I have found a few threads that have said that no one has reported issues with going to a bigger size and that going a step or two up will actually make the speedo a bit more accurate? Right now I am looking at the Kumho Ecsta AST (stock size) for the back and Falken Ziex ZE-512 for the front (185/60R14) Thoughts?

ON THE FRONT
I've stated this 10 or more times before but here goes.................My research shows that the Yokohama " S " Drive 185/55-14 will work on the front of all Spyders from 2008 to 2013 with or without fenders.........This is a very highly recommended tire ( according to Tire Rack ) and is a " V " speed rated tire .....It can be purchased for around $ 80 per tire.............Your welcome , Mike ..............PS as another bonus this tire has the largest footprint ( for similar sizes ) according to specs from Yokohama,...............and it will not upset the "Nanny"

As long as you keep the overall diameter pretty darn close to the original size; you'll be good to go!
You can plug in different tire sizes here, and see what the results will be.
Happy Hunting!!

Have not ran into a thread about this one. Thanks though! Looks like this will be my new front tire

Bob I know you've posted this before but there is a flaw here .....it's a Mathimatical measurement.......in the real world of tires what Goodyear calls a 225/50-15, is not what a B.F. Goodrich will measure out to be ( or probably anyone else's either ).......i.e. the circumference is not going to be the same ......and the Circumference of a tire is the only true factor that matters. The Tire Rack lists in the SPECS how many revolutions per mile each tire size will have, and this way you can accurately measure the same tire sizes from different makers against each other ..........Mike

Circumference Formula
Pi times the diameter (twice the radius) equals the circumference. You can run this on any calculator using the Pi symbol key. Revolutions per mile is 5280x12 divided by the circumference or 5280 divided by the (circumference divided by 12). The first way converts a mile in feet to a mile in inches. The second way converts the circumference in inches to circumference in feet.

You cannot simply divide the circumference into 5280 ft and get revs per mile. Tires are not round in use. They have a large flat spot where the contact the ground. Different tire constructions will result in tires of the same circumference using a different number of revs pre mile. Use the tire manufacturers specs to compare, not a mathematical calculation.
Also its difficult to compare widths. Tires are not flat across with square edges. The tire section widths can be the same with very different effective contact patches. Again, compare mfg specs, not size numbers.

That's no flaw Mike; at least not in the Math...
Manufacturing tolerances can always monkey things-up a bit...
But the raw numbers are always the best place to start the search!

Thanks for this INFO!!!!! Need a little help, guys. I need a new rear tire for my 2012 RT Limited. It's almost bald in middle after 9000 miles! So which one would you recommend? Need traction too! Would like a more milage tire. Then after I get the tire, do I just take to dealership and let them install? Do they mount on wheel etc.
Any help would be appreciated.
Thanks

2 + 2 = 4......MATH____________225/50-15 Goodyear = 950 revs per mile .........225/50-15 Kumho = 960 revs per mile ( these are not factual numbers just for demonstration purposes ) Both of these tires are the SAME listed size .......However their actual circumference is not the same ........Do you understand this now..........Sometimes the revs per mile are even further apart......Go to the Tire Rack Site and check their charts and you will see what I'm talking about ......jcthorne Post # 8 knows exactly what I'm talking and I'll bet RNET would also agree with this......Mike

Mike;
you're right.... the REV's PER MILE is determined by the depth of the tread.... @ least that's what i've been told.... the depth changes the diameter of the tire... for whatever reason, the 225 is to the bottom of the thread.... strange, i know... i wish i knew egg-zak-lee how the various tire manufacturers figured these things out.....
rock on pal..... when r u coming to TN....????

JCTHORNE in post # 8 above has a good explaination.......................I don't know the exact numbers ....the above ones you give could be correct......I do know the size ( REVS per mile ) is very close to Stock OEM.................The YOKO just has a much wider footprint in relation to it's overall width, which is only slightly wider than Stock
