My 1995 Ford F150 pick up truck has P235/75R/15 tires on it and I want to know if I can put P225's on instead without sacrificing performance, safety or load carrying capacity?

I would not. The numbers on the tires tell you alot about the dimensions of the tread and profile height. The P235 means the tread is 235mm in wide. The 75R means the tire profile height is 75% of 235mm, which means the profile height would be 176.25mm. What this means, if you change the tread width without changing the profile ratio, the tire will be either taller or shorter depending on what whay you go. By changing from P235/75R/15 to a P225/75R/15, the tire profile will be reduced to 168.75mm which is 7.5mm shorter. That might not sound like much, but keep in mind that is the profile, so at the top of the tire it would be 7.5mm, and at the bottom it would be 7.5mm shorter, which equals 15mm shorter tire all together. Since most vehicle have their speedometer pickup at the wheel, by changing the height of the tire that much, i am willing to bet your speedometer would be off, not to mention the other problems you might have with loads and performance. Hope this helps.

"meekeles2001" has the right idea and mathmatical breakdown is accurate ! I have a completely different vehicle a honda accord , wich I recently pute a lower and wider profiled tire and let me tell you this , I wouldnt do it again , the performance in corners increased a minimal amount but the overall ride decreased drasticly I am now able to feel every bumb , pothole , and imperfection in the road , and it sucks. If thats all you have right now they will work but, I think you will find a similar experience as I did , good luck

well, you're talking 20mm difference in the width of the tire, and 15mm difference in the sidewall.

i assume that you are planning on using the same rims.

you will be able to use those as a suitable replacement, unless you plan on either a) driving the vehicle hard around turns b) carrying heavy loads c) off-roading.

aside from that, you'll be fine using those tires as a replacement.

From what I can tell, just seems like you're decreasing the tread width. It does make the car easier to turn.

Load carrying solely depends on your truck's suspension. Tires do factor in, but only if you decrease the sidewall size, but you're not doing that.

as long as the tires have the same load rating. I wouldn't see a problem other than the speedometer will read faster than you are going and more miles will show on the truck.

the 235/75 is slightly wider (10mm) and taller than a 225/75 tire

Should be negligible difference if any....call a local tire store for load ratings of the two.

Yes you can I put 255/70/R17 on mine but mine called for 17" any way so mine are taller and wider than factory spec. hope this helps,

the only thing with that is with lower profile tires you cant haul as much because it would be setting down some what lower.
