After hitting a minor puddle and sliding across both highway lanes sideways, it's time for the nitto dr's to go. There still at 60 percent life or so, but have gotten much worse in rain driving lately. Can someone reccomend a decent, cheaper tire to replace? The 555 streets are staying on the front, but nitto only goes up to a 285 for rears. I need either 305 or 315 replacements, on 18 inch rims with a 35 percent profile. Hard to find tires in this size. Btw, no dragstrip use, just street driving. Thanks in advance for any input.
