Will Upgrading Tires Effect Sensors?

[eagle4495]

I was thinking about upgrading my stock tires (about 32”) to something closer to a 34” 35” on stock 17” rims.

This is something I typically do on my trucks but I was told by the dealership that it could screw up wheel spin sensors, abs, etc. (I’m not concerned about speedo changes)

 

Anyone who has upgraded tires experienced this issue, or is GMC just being a pain?

The dealer is right about creating problems with ABS and speedometer for sure.  I don't think the tire pressure sensors will be affected but transmission shift points might be off more than you'd like.  Putting 35's on 7.5 inch wide wheels is also not recommended by most tire makers.  Many tire stores will refuse to do so because of liability problems in a litigious society.  Not saying you shouldn't do it - just answering your question!.
