plus sizing tires?

[MrSo0h0o]

ive always been a bit foggy on this issue; i want to keep the same diameter rim size but do a "plus zero" change. The O.E. tire specs is 215-60-16. What would be a good plus zero size to go to? 225-55-16? Please help me out in understanding plus zero

Here is the plus zero for Gen6 camry copy/paste from discount tire direct 's website,

Plus Zero
205/65-16
225/60-16
235/55-16

My 9th Gen Corolla 06 has OEM 185/65/R14….how do I check for zeroing……& which tires sizes should I go for…..since I plan changing the wheels to 16”?

Thanks.

185-50-16 have about the same diameter if you must change the wheels. Seems silly but it's your buck.

Curious to learn how you smart guys use this to zero........I mean how do I calculate.........put in the figures of OEM in the left .....my OEM values 185/65/R14 shows 14 X 7 X ET10.........what do I do next?

Thanks.

Depends on wheel width for the 16s.

Use:
http://www.rims-n-tires.com/rt_specs.jsp

Plug in OEM size on the left, then test new size on the right, then you can compare overall tire/wheel diameters, ignore the widths/offsets for now.

your best bet is either

225/55/16
or
235/55/16

Never heard of the term plus sizing but im sure people do this to fit a wider tire on the rim. Wider tire = more contact = more grip blah blah blah.

Both tires mentioned above are going to be wider but will still have almost the same circumference and diamter as your stock wheels.

use that site and compare the sizes. I woudlve posted a screen shot but i dont have photosho on my laptop, and im lazy to turn my desktop on. But its pretty straight forwaerd

oh ya again i havent heard of the term plus sizing but i understand the concept.

Generally you have your stock tire which is what works with your speedometer.

With tires, you have 3 figures you have to read.

Eg. 225/55/r16
225 = the width of the rim. In this case , 225mm wide
55 = the ratio of the width. so 55 = 55% of 225 mm = 123.75mm
16 = of course the rim size.

Since your speedo is configured to your stock tire and its overall diameter, circumference and the amount it rotates in x amount of time, this is the most important thing when getting different size tires.

You would want to get a new tire that has an overall diameter the SAME as your stock tire to keep the speedo to work as it should, any bigger or smaller will make the speedo read the wrong numbers.

So since i explained that the middle number of a tire reading is the ratio of the width, you can adjust the numbers around so the over all diameter will match the same as your stock..

So pretty much this is what people do when they order bigger sized rims, they have a bigger rim BUT when they order tires, they need a lower profile tire (less side wall) to keep the same diameter as the stock wheel.

Hopefully you can understand this, i didnt really reread it and my brain isnt working so well right now since its almost 5 in the morning and im taking a study break.

Oh ya and remember, even though you can get various tire combinations to work out to be the same diameter, remember that you still have to look at width. You can put a 275mm wide tire on a 6" rim. As for width and fitting, someone else will have to chime in but for the sizes recommended, you should be fine

When you step up the width of the tire by 10mm (eg. 215 to 225), you then step down the profile by 5mm (eg. 60 to 55). Usually you only step up 10mm at most from stock as any more than this will give a fatter tire look, unless this is what you are trying to achieve.

This is some great info guys! I appreciate it! I read up some more on plus sizing and I think I pretty much get it. Like djkor said, I did see a pattern of 10mm and 5mm steps in width and profile, respectively, so a 225-55-16 tire would work for me. The only other thing I am wondering about is how it will look on my OEM rim. Will there be less or more sidewall? What effects will this have on driving? Would there be issues mounting such tire on my OEM rim?

thanks again guys, you are always there for me lol

There will be slightly less sidewall, but the tire will look a bit fatter, since it's wider slightly. But the overall diameter will be about the same as oem specifications. No issues mounting at all. Driving, if anything, might be slightly more grip, and be slightly bumpier, but not much, considering your going from a 60 profile to a 55 profile.

In theory, there should be the same amount of side wall to maintain the overall oem diameter. As stated before it might look fatter but probably not that much.

Why are you looking at a wider tire?
I think they would be a bit more expensive than the oem size, it does have better traction for the summer but since you live in a climate with snow, it might work against you with a wider tire. But 10mm probably isnt going to be a huge deal. Just think about a snow shoe when you think about wide tires, it just stays above the snow due to the surface area and a narrower tire would "cut" through the snow like a skate. So i think you should keep that in mind unless your getting dedicated winters and then these tires for the summer.
