can one have more then one tier on the mainland

You cannot "max out" your tier. You may own as much land as you wish anywhere in SL. Remember, though, that the concept of "tier" only applies on the mainland.  If you are on a private estate, you either own the whole thing or you pay rent to someone else who owns the whole thing.

On the Mainland, then, any tier beyond the first full region is assigned in half-region increments at a rate of US$97.50 per half region. So your land use fees for a full region ( 65, 536 sq m) is $195.00/month. If you own between 65,563 and 98,304 sq m, you pay an extra $97.50, and so on, a half region at a time. A higher level appears in your land use fees when you upgrade beyond a full region on the mainland. If you sell the land and move back to a tier of one full region or below, the system automatically tiers you down.

Thank you so much.

The difficulty with mainland tier is the size of the jumps between levels, particularly at the higher levels:

If you only want a little more than 65,536 m2 of land, it makes more sense to create an "Alt" (another Second Life account) and then make the Alt premium so the Alt can buy the extra land without the huge jump in tier level. I believe you are allowed up to 5 accounts. Each Alt that is made premium (by paying the premium membership fee for that Alt) will receive 512 m2 of automatic tier with no additional monthly charge, and the next few steps up in tier are relatively small steps for that Alt.

The Alt and your main account can deed your land to a group which your main and your Alt have control over. Group owned land gives you a bonus of 10% on your tier, but managing group owned land is complicated. It is very easy to make a mistake and be charged double tier for one month if you transfer land incorrectly to or from or between groups.
