is 205 65r 15 ok for 91 240sX?

[vancouverbc]

I have 205 60r 15 on front and want to replace rear tires with 20565r 15 because the tire is more popular/cheaper. I assume that the side wall is 5% or 10 mm larger so I have to make sure it clears suspension etc.

Looks like you answered your own question! It IS taller, but only marginally so. Effective gear ratio goes up, taller gearing, but it's only a minor change.

Thanks. The 65r are 20% cheaper for same tire.

Smaller contact patch though. maby check 195/65/15 instead & do all 4

I ended up buying 60r at walmart because they would not allow me to buy 65r as it is not the mfg recommended size.

do i need the fancy 90h feature? i do drive in a lot of rain. i was thinking of buying all season.

i guess i will by douglas 20560r15 like last time from walmart. they said they would rotate tires and repairs are free.

Just remember you'll have a thicker sidewall and your car will actually sit a little higer that before. I ran 205/60-15s before and if you want the closest size to stock rolling diameter, I'd recommend 205/55-15s. A bit more expensive but they look awesome and handle better.

umm...stock is 205/60/15

how would you change to stock by lowering aspect ratio when you already are stock?

[InsanityInc]

stock is a 195 series tire. To keep as close to stock as possible, you want a 205/55/15 tire.

iono my car had 205s on teardrop wheels when i got it and i thought i read that some of them came stock with 205s

All came stock with 195s. S13s, anyway.

[Onizuka]

205 width tires were an option.

[SmithSR]

true.both 190/60-15 and 205/60-15were original equipment fitment.

The 205/55-15 is an OK compromise.

[nismofly]

w00t for options!

eh i dont even roll on the stockers anymore anyway

[ArticDragon192]

195 was the most common width. 205/55-15s looks good. The sidewall is thinner than 205/60 and it handles better. The car understeers less when I push it.
