I can give you a visual of exactly why I hate 14" wheels. It cost me two $165 each tires. The only solution I found was to go with a 28" tall tire on a 14" wheel, or ride at a rock hard 8-9 psi tire pressure.Can someone explain what a pinch flat is and how sidewall height is involved.
And I'm willing to bet you are wrong. The OEM wheel has a 4+2 offset, and if you look at all the pictures, you will see the wheel is still at least an inch from being seated on the hub. A 4+3 offset gives you one more inch to play with, but it would still be against the tie rod end when fully seated on the hub.Yeah this doesn't prove anything as far as the 570sp and 12" rims are concerned. It only proves that stock rims don't fit. I'm willing to bet a 4+3 offset on a 12" rim will work on a 570sp.
Also this whole hating on 14" rims is a lack of knowledge and buying into misinformation. First of all 14" rims cause no more or no less pinch flats the 12" rims its the tires that wrap them is where the problem lies. In the off-road community the general rule of thumb is you want a 2:1 ratio tire to rim diameter. If the tire to rim ratio deviates to much from that ratio the user will run into problems. I run 26" tires on 14" rims and it is absolutely the best combo. To crunch some numbers my 26" BH 2.0's measure 26.75" @5psi. So on my 14" rim the ratio is 1.91:1. Don't buy into the misinformation 14" rims work just as good as 12" because there are pros and cons to each and basically the rider needs to make an informed purchase based on his riding style, needs, and environment.
I haven't noticed any difference in the amount of crap hitting me when riding. Depending on the angle you look at it, they may look pushed way out, or it may look virtually the same. They don't move things far enough out to be worried about fender flares.Does the 4+3 offset push your tires outside the fender Bob? Delta steels will replace mine stockers.Put them on a 12" wheel with a 4+3 offset and they will be perfect for your 570. I'm assuming they are 26-9-12 and 26-12-12 sizes.
