New tires question

Replaced all six tires on my 2002 Fleetwood Bounder recently. I noticed today that the tire dealer installed 245 on the rear, and 225 on the front. (Fleetwood recommends 245 all around). It appears this 225 tire does have a similar load rating as does the 245, but I wonder if mixing tire sizes front and rear is asking for trouble? Won't steering ability be compromised? I plan to call the tire place tomorrow and ask them what's what, but before I did I wanted to get a few educated opinions.
Thanks!!

If the coach had previously, and is supposed to have 245's - I would want 245's.

I agree, it has 245's for a reason, not only load ratings are important, but diameters are important also. changing diameters can change speedometer readings, it also can mess up computer controls for transmission shifting, and abs, if equipped. Make them put the correct tires on.

IMHO I would not want smaller tires than the MH came with.
What does your invoice show you paid for?

Dug up the invoice and it clearly specified 245 19.5s. The ones they put up front were Firestone 225. Called them today and they admitted their mistake and will correct it this week with the proper size 245. Unfortunately, the dealer I bought these from is 68 miles away, so hopefully driving it back to them won't cause any long term issues like what Franka548 mentioned?
I had all four rear replaced with Doublecoin 245, and fronts with Firestone 245. (Supposed to be 245 anyways)

As long as the 4 rear tires are the same size, nothing bad will happen on that end. The smaller front tires have a smaller "footprint" and may negatively affect steering and braking.

According to Les Schwab tire centers it's illegal to replace the OEM tires with smaller, lower rated ones. I've never checked to see if it's actually a law though.

Clhighman,
You will be ok for that short a distance, you might get an abs code, but I doubt it, If you do it will rectify itself when the right size is put on. The transmission shifting will relearn itself, also. Glad that you found the error before you had any problems. Now all you have to do is go enjoy.

Hopefully the back of the coach doesn't get to your destination before the front.

Not sure it "illegal" is correct word. Certainly going to lower load capacity is not smart as it increases the chance of overload and early tire failure.

Changing tire size on passenger cars is not as big an issue since cars have a Safety factor for load when it comes from the factory. There are some RVs that have no safety factor and I have heard of cases where RV tires were improperly selected such that the tires would be overloaded if more than 5psi was lost from the tire max.

Hope they are going to do right by you and consider a price break given that you found their "mistake" and its your time driving back and forth to the dealer.

I can't see any reason to replace your tires with smaller ones. There was a reason the Mfg. used the larger ones. Unless you like to tempt fate I would take them back.

Dealer should give you $$ for gas on the 136 mile round trip at 7 MPG or 20 gal@$3.50 = $70
