205 55 16 is essentially the size you should be running, i’d stick with it, maybe drop down to a 50 in the front, but i wouldn’t go less than that in the back it effects your speedo and is annoying imo, wastes gas too ---

lucidsnow. so in your opinion, 225/55/R16 would be the max i shud go with the size of rim i have? Now would that be for all four rims? heatw. i guess i can stick to my 205/55/R16 but i want to have a bit more grip with what i have. how bout this? 215/55/R16 for the front and 225/55/R16 for the rear? ---

I have 16x7 +25s in the front with 205/55/16 Potenza RE01s… Have never chirped them or broken them loose, they look nice and square too. ---

[http://www.onlineconversion.com/tire\_size\_conversion.htm](http://www.onlineconversion.com/tire_size_conversion.htm) do some homework. put in your stock tire size to get the diameter. then put in the size you want. try to get it dead on or as close as possible. stock size on my s13 is 195/60R15 Front which = 24.2" stock size on my s13 is 205/60R15 Rear which = 24.7" a/m 16x7 Front 195/55R16 = 24.4" a/m 16x7 Rear 205/55R16 = 24.9" i’m going to go wider in the rear once the rears are done. but keep the same height and not to much bulge. there fore i am going to try and get a 245/45R16 which essentially puts me back to 24.7" in the rear. plug and play some numbers. then look up a pic on the web of your size tire on your size rim to see if thats what your looking for. i think a 245/45 is gonna have to much bulge to even fit proper. any one know? ---

If the tire u put on the rim is to large it will bulge on the sides and all that tire tread bulging won’t touch the ground properly and in essence you’ll have a smaller contact patch anyway, stick to a 205. ---

I was pretty confused when the diameter increased by increasing the tire width. That simply does not make sense to me. Also I’ve seen 225/65/16 tires that are WAY wider than 225/60/15’s IRL. Can someone explain why? ---

Dude just go with 205s on a 7" and make sure they’re GOOD tires. It’ll make the world of a difference. For example, compare 205/55/16 Potenza RE01s to 215/55/16 Toyo Proxes TPTs; i ran both those tires last year. That 10 mm difference wont mean shit. The RE01s are a much grippier tire and you’ll notice it. Edit: What car is this for? KA? SR? just curious. ---

87s15lt1. i tried the calculator and this is what i got: my current tire size: 205/55/R16 Front & Rear @ 24.9" my new tire size: 225/50/R16 @ 24.9" or 245/45/R16 @ 24.7" so my best bet here is the “225/50/R16” option right? those would be for the front … cud i use the 2nd option of having the “245/45/R16” in the rear? or jus stay 225/50/R16 all around? because i do want to have a **bit** of a wider tire in the rear for grip. ---

Wider tires does not always mean more grip, i dont understand why you have to use that calculator. If the tires are too wide for your rims, you’ll get bulge and your tires will flex when you corner. Go outside, look at your tires, are they square, bulged, stretched? Chances are they’re square. Just take the current size you have and go with some really good tires. Dunlop Direzza Z1starspec Toyo T1Rs Bridgestone Potenza RE 01s, 070s 050s Falken FK452s Falken FK452s and Federal 595s are pretty far apart. Go with the 452s if you want grip and get them 205/55/16 ---

You cant have stretch and bulge unless your tire is… well defective or old. Stretch is when your tire is too thin relative to the rim Bulge is when your tire is too wide relative to the rim. Tread doesnt need to line up PERFECTly with the rim. Tire manufacturers use different standards when measuring their tires. a 205 from Toyo and a 205 from Bridgestone may not be the exact same width when seated on a rim. Dont go anything larger than 215 on a 7 IMO. [Next page](https://forums.speedlife.net/t/tire-size-for-16x7s/120184.md?page=2)
