Ideal tire size for 15's

hellow ladies and gents....need suggestions here..

ok i have 15's and the original size is 195/55/15...i want a wider track so i was wondering what would be the best size...205/60 15???

my car is civic 4dr..lowered 1.7 in the front and 1.5 at the back..so what size would fit the best and give me wider track.... i ant wide track and lower size from the rims...like low profile but not that low..sorry if this is confusing.. thanks for understanding ppl.

thanks in advance and MERRY XMAS to everyone

if you want a wider tire then get a 205/55/15 or 215/55/15.
I personally use 205/50/15's on my SIR wheels on my 95 coupe, which is lowered 1.8" and have no problems.

best fit is 205/50/15 which is 23.1" overall, 195/55/15 is 23.5" so 205/50/15 is also the closest to stock you can get. i've heard 215 will rub, so 205/50/15 is what your after. also, plenty of tire options in that size. I run Hankook R-S2 Z212's in 205/50/15 and love em

205/55/15 is 23.9", so would also work, but less tire choice in thiis size compared to 205/50/15

205/60/15 is 24.7". so 1.2" taller them stock

195/50/15 is closer to stock than 205/50/15s are if you have the stock 13 inch rims. i'm not so sure on the size of the 14s though so i can't say anything. i use to run 195/50/15s on my LS mesh but then switched to 205/50/15 on the same rims. i found that the 195s had a quicker response than the 205 but that's probably because stock honda rims are like 6 inches only. i'm sure if i mounted them on wider rims it'd be better. rim size is important to how wide of a tire you get because the thicker rim you have on the same tire, it will reduce the tire wall flex which will respond faster.

205/50/15 is for 5.5-7 rim" but ya i know what you mean.

My 205/50/15 on 5.5" steelies makes the sidewall flex alot more then 7" wide rim would, exactly the reason i'm going with 15x7 in spring. response with 5.5" is slow

205/50/15 on oem rims (blades/sir) is perfect, helps car handle better because the tires are wider imo.

Can you explain with real examples? Numbers etc.

Easiest way to figure out tire sizes is by this (www.tirerack.com) otherwise use this method.

205/40/R17

205 is the width of the tire in mm.

40 is the percentage of the width of the tire creating th sidewall. Eample the sidewall is 40% of 205mm.

R is the speed rating.

17 is the rim diameter.

So on to how you use this if you have a 195/50/R15 your next widest tire you would look at would be a 205/45/R15 to keep the closest to the same overall diameter. When you add to the width you need to take away from the sidewall percentage. You can go up in rim sizes too like a 205/40/R16. Now remember that all manufactures diameters are different from each other such as a Yokohama's overall diameter could be 24.0 and a Dunlops could be 23.7. One whole inch will equate to your speedo being out approxiamtely 7-10km/h at 100km/h on your speedo.

what do you mean explain with real examples? what's more real than first hand experience? i bought my 205s right after the 195s and the 195s had better response. turn in response was quicker than the 205 but it's winter and i have yet to test my 205s to the limit to see what the overall grip is. i've tested them on on ramps and off ramps but not to the absolute limit like i've done before on the 195s. honestly, i don't mind the 205s but they just seem more sluggish to me compared to the 195 on a SIX INCH rim. you need wider rims to maximize the tire width so there's less flex in the tire walls. driving on the street is not noticable but once you reach higher speeds on highway you can notice the difference in lane changes. the 195s did not give me as much grip as i wanted but they are 512 ziex so i can't expect them to handle like azenis RT-615.


i have the program on my computer to calculate the tire size and speed difference. overall diameter of 195/50/15 is 22.68 which will be 0.13mph faster at 70mph compared to stock 175/70/13 but i'm not sure on the 14s. 205/50/15's overall diameter is 23.08 which will be 1.36mph faster at 70mph. 205/45/15's overall diameter is 22.26 which will be 1.3mph SLOWER than actual reading. imo i'd go with 205/50/15 for the extra comfort of the thicker side wall. i'd go 45s if i go 16s though. 205/45/15 is only closer to stock spec by .06 than 205/50/15 which i don't think you'll be able to notice.
