Rim/Tyre size question

Google CMA mag and this comes up.

If the total diameter of wheel with tyre is smaller after you replace the 19 inch rim with an 18 inch, the steering geometry might change because the rake becomes similar to what you have when the bike is accelerating under normal circumstances, although the bike might not actually be accelerating. If your bike is already oversteering in corners with the bigger rear wheel, it might oversteer more with a slightly smaller one. You can probably correct it by adjusting the ride height at the rear with the shocks

I have used Avons and TT100s. The only negative that I found is that when used on the front, the continuous center groove on the Dunlop seemed to have a weave issue with grooved pavement or grated bridge decks. I have avoided tires with this kind of groove ever since.

Bryan Tryee, invented the front breast link, helm's radius rod, to solve the rain groove hunting on then available center groove vintage tires on Calif free ways. Easiest link to fit and gives more ease/stability than common link head steady. Comnoz saw the wisdom to do one of his own.

My sense is wider tires, grip more, right up till they don't more suddenly than narrower, so unless a maniac traction tester, the skinnier the tire profile, the more accurate the handling and warning - ease/chance to recover over doing it. As as never hear any one mentioning tire sounds or sliding front on joy rides - likely don't matter a whit worth what ya fit as ain't got a good enough cycle or skills to even appreciate various tire combos features. Of course those not ever needing survival level braking, ALL say fit smallest tire on front for best ease - steering faster into unexpected brake needs. If too easy to spin rear in turns fit a bigger tire, if not, enjoy heavy hiking boots heavy duty sluggish security.

the front link on mine has NO effect on groove hunting it is a tire design issue.
