Can I fit 205/50R15 tire on my Versa 1.8SL 2008

[LaKate]

I can have a deal on almost new winter tire. The size is 205/50R15. Is it going to fit on my Versa ? I think my speedo is going to be off a bit and that is no problem for me but beside that is there any other reason I shouldn't take them ?

yes they will fit, but they are over 1 inch shorter in overall hieght and your speedo will be off by almost 5 mph.personally i wouldnt do it

why would your speedo be off? there are speed sensors... when i had my 20's on the speedo was correct...

superskunkur speedo was 3.5% off

LaKateur speedo will be 5.7% off

blind_snyperto be 5mph off, you have to be going almost 90 mph with 205/50/15 %)

Very useful tool for comparing tire sizes (Canadian members might find it slightly less useful as it only has US 5mm sizes and not the even sizes available in Canada):http://www.miata.net/garage/tirecalc.html

Keep in mind that speedo inaccuracy is not linear. It's a percentage. The discrepancy increases as speed increases. A 3.5% difference is under 1mph off at 25mph, and 2.5 mph off at 70mph.With my short-geared rear end, I have a discrepancy of about 4mph at 25mph, but at 70 it shoots up to 10!

205-60-15 would be a better choice as they are very very close to the stock 185-65's rolling diameter.

there are speed sensors...

Yes. And those speed sensors (actually, it's singular sensor) use rotational speed from the transmission output shaft to determine speed. So if you have tires with smaller-than-stock rolling diameter, the speedo will read high. Taller tires will read low.

On the Versa? Doubtful. How do you know?

3.4, what ever

well i should have mentioned that was correct at 30mph... those radars that show you how fast youre going is how i found out... i still dont understand how 205/50/r15 would be off more than 225/30/r20... i guess somethings are better left unknown... but im sure one of you will explain it to me...

225-30 is lower profile than I was expecting (I figured with such a narrow tread for a 20'' tire you'd have a higher sidewall ratio than that). It actually is pretty close to stock (only about 6.6% off). So at 30, it would look very close (you'd actually be doing about 32).

The 205 is a smaller change, and the other direction. It puts you at about 2 mph off at 60 rather than 30. 60 is really 58.

But I never said the two were drastically different. I just doubted your statement that your 20s were accurate, thinking you'd need to run rubber bands on the wheels to be close. I was wrong, since you WERE running rubber bands.
