You might consider posting the same question only one time and not eight

As for your question yes they will fit but the speedometer will read slow.

 

Yeah, bigger tires = screwed up speedo readings. It can be corrected but sometimes its not even worth it.

 

I have LS1 Edit, and should be able to correct it with that.

yeah the speedometer is only affected by .06mph

 

Then your math is wrong. In perfect terms when you go from a 225/50/16 to a 245/50/16 your speedometer will read slow by 3.2%. Your .06 mph example will only be true when the car is traveling approx 2 mph

60 mph indicated = 62 mph actual; 3.2% difference.

There's a nifty tire size calculator here

 

Damon,

According to the calculator you linked to, the 245's are actually .7% SLOWER than the 225's.

That is when you are going 60, your speedo reads 59.6

 

245/45 16 was the hot auto-X setup in the 90s.

 

No, DamonB is correct. You used a 245/45/16 in the calculation, the question was for a 245/50/16.

Mark

 

my apologies - you two are correct sir

 

i was never good at math lol

 

I run 245/50/16's in the rear. I havn't had any problems at all. Yes your speedo will be off some, but if your running a different final drive like I am, it will be off anyways.

You can run LS1 edit on an FD???

 

i know someone that has run 255/50/16 in the back

 

245/45/17 on my back lol
