Tire Size on 16" rims to keep the speedo on task!

[BboyOxygen]

Would I go with a 50 series on a 16" rim for my 89 240sx?  I'm thinking either 50 or 55.. Anyone know for sure?

I know for sure!  I posted a link to a tire size calculator in the FAQ section, and it's still on the first page.  The title of the thread is "Tire Size Calculator."
Check with that, it will tell you the spedo difference with any combination of rims and tires.

That depends on tire width.

Tire height should be 24"-25".

205/55-16 (stock S14 5-lug) is 24.9"
215/50-16 is 24.5"
225/50-16 (stock 300ZX-TT front) is 24.9"
235/45-16 is 24.3"
245/45-16 (stock 300ZX-TT rear) is 24.7"
