EZPZ Tire sizing calculator

[Wanted33]

I don't know if this calculator has been posted. For those like me that are wondering what size tire you want on your Bronco here's one that wraps it up in a neat package. Just put your factory size in, and them the sizes you are thinking about, and it shows you the difference in 5 categories.

Handy. I also downloaded an app once that's very similar.

Similar to this one, which I found very helpful in the past: https://tiresize.com/comparison/

This is also handy to compare stock tires:

Do any of them calculate how wheel width impacts the dimensions? Not wheel diameter…

can someone give me an example of a 17” “true 35” tire size, as I’ve heard many refer to the SAS tires as “not true 35s”? The first link says 305/75/17 is exactly 35”, but tire rack shows no tires for this

35*12.5*15 for example

Here's one I've used several times in the past when sizing after market wheels/tires. Allows you to compare current wheel setup to new wheel setup -- https://rimsntires.com/specspro.jsp

This is the one I use: Tire Size Calculator - Compare Tire Sizes | Tacoma World

Remember, these are just estimates. Tire manufacturers are somewhat random in how accurate their sizes are, plus, the actual sizes change a bit based on the width of the wheel. You still need to look at the manufacturers specs to see what the actual size is they claim, even though it's not always accurate either.

the 315-70-17 is 34.4" per the chart but the Goodyear Wrangler MT lists 34.7, CooperDiscoverer 34.6 and others is a range from 34.4 to 34.7. The calculation is an estimate for a generic tire size with different manufacturers actually building tires to their own size. Inflation pressure also effects tire diameter.

Look at the offset calculator at the tiresize.com site.

Here's a Base 16 vs a 285/75-17 on +25mm wheels.
That info on the right is precious.
