Do I need to get an alignment?
Hi guys I just switched from 17" to my 15" winter set. Do I need to get an alignment? If so would i need to get it done everytime I switch from 17" to 15"?

You shouldn't need an alignment if all of your 17" tire sizes match, and your 15" tire sizes match, as well as both sets of rim widths. Changing all the tires, as long as the set of tires are all the same size, should not affect your alignment. I hope that all makes sense. PM me if you have any questions.

Doesn't matter what size wheel or tire you put on the car, it doesn't change the alignment or the alignment requirements.
No, you don't need to get an alignment. |

yes it does, if you run... say 205/40/17 on the front and 215/35R17 on the back, and for the winter you run 185/XXR15 all the way around, then yes you do need an alignment due to the fact that the difference in tire size will affect your camber/ caster. So it does matter. It may not make enough of a difference in your alignment to be concerned about it, but to be correct it needs an alignment in that situation. Now if you run 205/40R17 all the way around on one set of rims, and 185/60R15 on the other set, then there is absolutly no reason to get an alignment because the tires being a matching set will not affect any of your alignment geometry. You may flame me because I'm the new guy, but I am a ASE Master Tech, and I work as a Senior Mechanic for the State.

You would only need an alignment if you custom calibrated your "current" alignment to work with a certain configuration of wheel/tire. Aside from that...I don't see a reason.

Does your camber AND/OR caster change when you run the car up on a ramp? Because thats technically what you're doing.... dang. I'll stop. This is going to get stupid. Tires do not effect camber and caster. Camber and caster effects tires. Unless you've got some TOO MUCH GRIP status, and causes those bolts to get loose, some how. Are you truly a ASE Master Tech? I felt myself getting pulled hard into this one... |
