Finally completed my 5 lug conversion. But why is my oil temp goes up faster than before. Is it because I have a lower diameter and wider tires? Or just a coincidence that after my 5 lug conversion there was another issue that makes my oil goes up faster than before. On the same weather condition around 65 degrees F, I used to drive my car for about 3 miles around city which my oil temp does not goes up immediately and I only get around 180 degrees but today I drove it and my temp went to 200.
Any experienced you have had or anyone can help me figure out? Thanks again my fellow teeners and God Bless! |

Your engine is spinning significantly faster to go the same speed.
Stock tire diameter is 25.7" 185/65/15 is 24.5" 205/50/15 is 23.07" The radius (half the diameter) of the tire is what is relevant. You went from 1/2" shorter than stock to a full 1.3" shorter. This is awesome when autocrossing. For daily street driving its kind of a drag buzzing along at freeway speeds and 3500 rpm. The owners manual shows that with stock tires @ 65 mph is about 2800rpm. Many of us go to the 16" rims so we can keep a low profile tire. You could use a taller tire like 205/60/15 to get that height back to 24.7" 200* is not a bad temp at all. Hopefully on a hot day you stay cool. Check tire rack for tire diameters. The diameters are all slightly different, but not to far off. Check out Tire Rack for exact specs on available tires. Car looks great. I love BBB! |
