Dealer upgrading tires

Hi. New to the forum. Bout to pull the trigger and order a 2015 dcsb sr5 2.7. My question is anyone had luck or tried to get tires upgraded to a 265. Don't wana waste good tires that come with it upgrading and don't wana wait til they're worn out either.

 

I know when I asked my dealer they basically said "you buy them and we will install them for free". Still end up with the stock ones though.

But there is a bit of a market for the stock tires/rims so you should be able to just buy news ones yourself and have them installed where ever and just sell the stock ones locally.
