Tire Size

[s2tigger]

Okay, I know that this question is not about winter tires, but... Right now I have Axis - Lenso VPD RIMS - 17"/ 7" with Kumho Ecsta Supra 712 - 215/45 on my 1992 Camry. I'm wondering what the widest tires I can put on the RIMS that will still clear my fender wells are. Any idea?

225

Ya sure that's the largest size I can fit?

On your rims? Yes.

Is it worth getting the larger tires, next time I need em, in your opinion?

depends on you driving style really. If you require the extra tire width, go a head.

I'm making an assumption you have a 4 banger.

If you really want to go 225 width:

225/40 r17 (2.67% smaller than OE)
225/45 r17 (0.91% larger than OE)...this size is closer overall to OE 195/70 r14

You're correct, I do have a four banger.

I think I'll probably end up going with the 225/45 r17 (0.91% larger than OE)...this size is closer overall to OE 195/70 r14. What do you mean though when you say "(0.91% larger than OE)...this size is closer overall to OE 195/70 r14"? They won't rub on the fender wells or anything, right?

What I mean is overall tire height (diameter). A lot of people use circumference, which the speedometer and odometer uses.

For example the OE 195/70 r14 tires are about 24.78 inches in height (diameter).

The basic formula is (you can do it in Excel, to compare):

195*70/100/25.4*2 + 14

the tire width times the aspect ratio (70/100) divided 25.4 (mm to inch conversion) times 2 (total sidewall height) + 14 (wheel diameter).

What is generally used is to go not more than 3% larger or smaller than the OEM size. A larger diameter (circumference) means the speedometer will read slower and odometer will read slower. A smaller tire means the opposite.

Okay, I just wanted to make sure I knew what you were talking about. I understand that the 225/45 r17 would just be wider than my current tires, so there would be no additional change in the speedometer or odometer outside of my current change, which isn't much at all. So, that being said... Would there be any really noticable change in grip and handling by going with the 225 versus the 215? Will they rub on the fender wells at all? Will they stick out from the side of my car?

Why complicates things when you can use...

sometimes it's nice to know the math behind it.
